Refuting troon delusion, basics, terms and people involved. - As I promised

[Glowie]

I'm a phonefag so this will look like shit

I'd like to start off this thread by covering the basics, terms, fields, people and places

Then continue to elaborate on these people and their fallacious findings, cover terms in specific detail and then cover troon semantics, their talking points and fallacies they use when cornered. I hope that this thread will serve you all well


Note
Hard Science: a field where experiments and findings are the same no matter how many times studies and experiments no matter what
Soft Science: Fields that do not subject themselves to strict rules, rigor or scrunity, findings in these fields are subjective and are prone to human error as such
Pseudo-science/Quackery: Also known as bullshit, snake oil and simply bad science.
Everything under this umbrella is proven wrong when put under scientific scrunity
Fields. Unlike soft science quackery can dimissed by proof or using soft science
Biology: Hard science which encompasses genetics, anatomy and other sub categories or combinations with other hard science fields
Psychology: Soft Science, which includes behaviour, developmental and many other fields. Hard Science often mix with this one, where pharmacology meets psychology and created psychiatric practice.
Sexology: Quackery found in Weimar Republic in year 1919 in Institut für Sexualwissenschaft, This institute didn't subject itself to peer review, not even once. Whatever was left after third Reich burned the place was picked up by John Money who his fellow Pedophile Alfred Kinsey published series of papers and studies all of which are found on bad science and outright lies.

Terms
Gender: Term coined to be used by John Money in psychology to muddle the water between biological sex and subjective term of self reported or assigned identity
Sex: Biological terms for biological sex which has only two. Male and female.
Transgerism: Idea where series of delusional surgeries and hormones can turn a biological man into a woman and vice versa.

Gender affirming surgery/sex change: example how John Money's bullshit mixes in with real science. More of this later
Cisgender: people with chromosomal abnormalities instead of usual XY and XX pair these include Jacob's syndrome with XYY pairing and Klinefelter syndrome with XXY pair. These are two examples. Number of people with these mutations are less than 1% of world population. There are more to name to say the least, more in detail later.

People:

Alfred Kinsey
the father of sex ed in America and co creator of modern sexology with

John Money
Father of gender identity movement and co creator of modern sexology. Much like his buddy Alfred, John resorted to false reporting, outright lies and peer review.

Magnus Hirschfeld: German physician during Weimar Republic who created archaic sexology and performed first gender reassignment surgery in history.
Since he was only one of the transgerism trifecta with medical degree, John Money and Alfred Kinsey plagiarized the shit out of his work.

Places
Institut für Sexualwissenschaft
The institute and clinic where Magnus worked, sold passports to transvestite prostitutes and preformed first ever trans related surgery in history.
Kinsey Institute.
Mecca for transgenderism everything is done here and more John Money is in hall of fame.

Alright you fucking glownigger. Get to the point.

Modern transgerism is found on John Money's twin study on David Reimer, whose penis was mutilated after electronic circumcision device malfunctioned. David ever since young age had psychological issues since he couldn't compare to other boys or to his brother and father in this case, due to the fact he did not have a penis.
Long story short David's parents had the idea to bring David to John Money to give him help, since it was impossible to reconstruct a ruined phallus at the time.
Long story short after forcing two pre teen boys to have pretend sex, force David to wear girl's clothes and eventually take hormones to create fake breasts.
David snapped out of this phase as he got older, surgically removed the fake tits, then he got married, fully identified as a male and got married, later in life David developed schizophrenia likely caused by echelopathy caused by hormones he took.

Why does this matter you ask?

John Money was busy writing his study all the while omitting details and outright lying in paper. John Money didn't believe in biology at all and came up with the idea that gender identity is innate rather than
learned, John money wasn't a biologist and he ignored the fact he was treating a young boy with a ruined tallywhacker then proceeded to groom David and David's parents. Any behavioural psychologist worth their salt like Maslow would've called this out, but we are talking about a man who had a private practice and tried to normalize pedophilia, much like his buddy Kinsey, so he didn't have much of a moral compass.
This being 60s feminists during sexual revolution paraded John Money and his "research", which is why left leaning academia accepted this as a norm in United States. This is the bedrock of transgenderism.

No shit nigger, I knew that already. So now what.

Listen newfren. That was a mere refresher course. Now we will get to meat and potatoes of it all, deconstruction of Tranny arguments.
Others are longer and others are shorter. There are possible conversation you might have with someone, so I formatted then as such. Your answer to each claim is written below each one

The usual arguments

1. Gender is social construct!
Yes you're right gender is a term made up by a quack doctor. Gender is a nonsense term in psychology, there are only two major BIOLOGICAL sexes, male and female with few rare exceptions to this.

2. But trans identity is innate, it's genetic!
Closest correlation to this are specific genes that are found in homosexuals, there aren't ANY genetic proof that people are driven to attempt change their sex at onset.

3. But muh male and female brain
Debunked myth MRIs show male and female brains ONLY differ in size, you get either according to your sex Source chromosomes. If you have abnormalities, that doesn't make transgender ideology any more valid they're rare exceptions

4. But muh dysphoria
Get Therapy, self harm by proxy isn't healthy just because you feel like it isn't okay, nor is it a right choice.

5. Intersex make are trans!
People with chromosomal disorders didn't choose lose to in genetic lottery, not did they decide to lop off body parts in utero. Furthermore they didn't transition as TRANSgendism imply.

6. Sex spectrum is real!
No sorry you are either a man or a woman existence of that 1%~ (Source) does not make trans existence valid, you are born either as a man or a woman and you will die as sex you're born as. Sex spectrum is sexology and gender spectrum pretending to be scientific

7. But my top and bottom surgeries!
For MTF all you did was cutting a deep hole connect extra hole to your prostrate, something that is present in men only. Your colon seeps bacterial colonies into your neovag, causing festering and smelling infections. Your breasts are composed of fat and they can't lactate, if they're implants they're literal fake tits.
Sorry for FTM, scooping up your breasts and making a intermittent catheter covered with skin that grows hair. You won't grow chest hair and develop proper pectorals ever with permanent scar running across your chest where your breasts are supposed to be.
Even if you decide to remove your ovaries and womb you're still a woman

8. Well I identify as [insert gender, species and soul from Tumblr here]
Doesn't matter, playing pretend does not validate you, if you claim to be something else than human, prove it.

9. You just hate trans!
Okay.

Additional notes
Since there is no genetic evidence for trans identity, look underlying mental illnesses, disorders like Autism or Downs syndrome, all of which affect healthy sexual development.

To repeat myself cancer patients who have their prostate, breast ovum or womb for men respectively. Only parts of anatomy are missing. Surgeries do not change sex or make anyone more, less or something else entirely.

Since we established that trans identity is result of nurture, trauma, grooming, peer pressure, one's parents, schools and other transgenders spreading their anti science dogma like a religion.

If you feel like it mention to transgenders that their surgery obsessed ideology insult cancer survivors. They had to lop off organs to survive, transgender do surgeries for superficial reasons.

And if they say that HRT is necessary, mention insulin, immune suppressants for organ transplants, anti convulsants for epileptics and HAART using HIV victims. Transgender claim that pills that only cause superficial changes belong same group as these drugs.

This is a rough OP and I'll add sources and papers later when I have more time, also I'm writing this in a rush, so my grammar is atrocious.

 

[Looney Troons]

1) as a fellow phonefag, and proud of it, get a text editor, especially for longer posts like this. The one that comes stock should be fine. Don’t rely on the XenForo editor.

2) I read the entire thing. Where I found it interesting in parts, I think this entire thing could have been summarized by simply stating that troons are delusional

 

[Dawn Pennis]

You mixed cisgender with intersex.
Cisgender is identifying as the sex you were born as AKA being normal.
Intersex is chromosome disorder like XXY and hermaphroditism.
You made some spelling errors and mentioned David Reimer getting married twice.
Other than that I enjoyed this, drop some sources and format this better. Good work OP.

 

[Ronnie McNutt]

nice post, but you should really add sources to why that specific thing isn't the case, just saying "it has been debunked" without any actual source will give trannies more ammo to use against you

 

[Charactis]

There is a lot of room for improvement in the OP which goes on a massive tangent. Make it constrained, concise: highlight the biological sex and gender dichotomy right from the start, showcase what they are and how or why they are incompatible, then use sources and/or definitions to justify your premise rather than just start writing like a dishevelled Redditor. It also doesn’t help to be so dismissive and trying to be authoritative with foregone conclusions as it opens you up to easy criticism.

To wit, gender as a social construct. It doesn’t matter who coined the term: Gender as a construct where people are arbitrarily assigned roles or discriminated against based solely on their physiological properties was and is observable across all cultures and has a richer literature than a single straw-man the OP keeps ranting on about.

The only reason why this even merits a response are the current problems of this community with the trans movement (or certain actors that claim to be part of that movement.) Writing so poorly and aggressively just gives them more reason to disparage everyone on here as an idiot. Don’t be an idiot. Apply yourself.

When the guy who coined it did so as an excuse to ruin a child's life, and it is still being used for that, yes it matters.

 

[murph]

I think it's helpful to say that there are no human hermaphrodites. Intersex people are either male or female, they are not a third sex. There is no human being that produces both egg and sperm.

Also to the 41% issue, there's evidence that the surgery results in "considerably higher risks for mortality, suicidal behaviour, and psychiatric morbidity than the general population."

Good write up.

OK, let me sperg for a bit too:

Gender is a nonsense term in psychology, there are only two major BIOLOGICAL sexes, male and female with few rare exceptions to this.

Gender exists as a role, insofar someone can pretend to be of different sex and LARP their role. Semantics - people can genderbend, but not sexbend (unless a troon lol) when doing that. What troon apologia does is a category error - thinking that gender can somehow influence one's sex.

Debunked myth MRIs show male and female brains ONLY differ in size,

This sounds dubious. While it's popular in cathedral narratives to *deny* prenatal sex-differentiation of brain, there is hard evidence for differences in amygdala-neocortex regulation, especially when it comes to very ancient impulses, such as aggression.

No sorry you are either a man or a woman existence of that 1% does not make trans existence valid, you are born either as a man or a woman and you will die as sex you're born as. Sex spectrum is sexology and gender spectrum pretending to be scientific.

There's a variance in sex differentiation. Some men are less aggro, and thus become more feminine and passive-aggressive, some women are more aggro, so become more masc - and this acts as a modifier of their psychsexual behavior in comparable manner how a 6'2 snoo snoo woman can overpower 4'9 manlet. Kinsey scale is bollocks in that it claims this mechanic can entirely flip your sexual attraction (ie that there's somehow a sign on a scale). But variance can only explain certain aspects of bisexuality - in particular, prison gay - big bad bubba chad dominating twinks, but not that much else. My personal theory is that various forms of faggotry as seen on twitter is over-socialized form of bisexuality taken to the extreme.

 

[DaBigBopper]

We have a thread on Kinsey here. Someone went into how most of his data is unironically sourced from pedos in jail. The class he taught asked really fucking odd questions that you could interpret as 'yes, this lady who's only been fucked in the missionary position for the sole purpose of procreation is actually hyper-masculine because we interpreted the results'.

Tranny delusions are akin to someone deep within a delusion. Basically like someone in the end stages of dementia where they can recognize their granddaughters face, but confuse it with their long dead wife. Or a schizo so deep that challenging the delusion is a danger to those around them because their reality is based upon that now.
Trannies who fully mutilate themselves are basically the biggest danger because they're too deep to turn back. A chick who took some Testosterone might just have a deeper voice, a big clit, and some odd muscle development. A guy who took Estrogen will have bone problems, dick problems, and hair growth problems, but can outwardly continue his life. The ones who fully mutilate themselves are fucked. It's worse then men who got scalped by Natives during the early days of America. They are permanently disfigured in a way that outs them as being retarded.
Worse is that immune problems arise when you get your dick, or your tits removed and get arm sausage.

Hard Science: a field where experiments and findings are the same no matter how many times studies and experiments no matter what
Soft Science: Fields that do not subject themselves to strict rules, rigor or scrunity, findings in these fields are subjective and are prone to human error as such

It's hard to find a good or precise definition of what makes a science "hard" or "soft," and there's debate over the terms themselves. While a good experiment should have consistent findings (high accuracy), that's not exactly a definition of "hard science." Similarly, "soft sciences" usually still have strict rules and scrutiny; they often follow the scientific method and the findings are peer reviewed before publication. If I had to define the terms (short of "STEM and non-STEM") I'd say "soft science" focuses more on large, complex systems (behavior development, group dynamics, etc.) while "hard science" focuses on more discrete systems (cell function, chemical reactions, etc.).

Cisgender: people with chromosomal abnormalities instead of usual XY and XX pair these include Jacob's syndrome with XYY pairing and Klinefelter syndrome with XXY pair. These are two examples. Number of people with these mutations are less than 1% of world population. There are more to name to say the least, more in detail later.

Cisgender just means "not-transgender." So an XX female or XY male. I think I've seen shit like XXY, XY gonadal dysgenesis, and hermaphroditism labeled as "intersex."

1. Gender is social construct!
Yes you're right gender is a term made up by a quack doctor. Gender is a nonsense term in psychology, there are only two major BIOLOGICAL sexes, male and female with few rare exceptions to this.

The issue of "gender being a social construct" is a bit more complex than I think either side realizes (tldr, it is but it also isn't), but rather than belabor the point, I'll just say this is probably the weakest pro-troon argument when it's really thought about (gender =/ sex but being a different gender means they should change their sex?)

2. But trans identity is innate, it's genetic!
Closest correlation to this are specific genes that are found in homosexuals, there aren't ANY genetic proof that people are driven to attempt change their sex at onset.

Another thing I can go on about (tldr, read up on the biopsychosocial theory) but I will say in general I'm not aware of any specific genes found in homosexuals. Usually troons like saying it's innate without saying it's genetic anyway, with the strongest theory I've seen being about low prenatal testosterone during a critical period (though I don't think this sufficiently explains the phenomena).

3. But muh male and female brain
Debunked myth MRIs show male and female brains ONLY differ in size, you get either according to your sex chromosomes. If you have abnormalities, that doesn't make transgender ideology any more valid they're rare exceptions

There's actually a decent number of structural and functional differences between male and female brains. And while prenatal testosterone does play a role in male brain development and patterning, it's again not the whole picture (so your troon male doesn't really have a "female brain")

Your breasts are composed of fat and they can't lactate

Female breasts are composed of fat too. Also, biological men can lactate (pubmed article).

Background history what troonism to explain what anti science horse shit, simple "John Money lied, people died"

I wrote this out of back of my head, DDoS attack threw wrench into my editing and sourcing shit properly to cover every argument.

I can only work on this properly now. I promised to write this on Telegram and I did so.

 

[Ultrapenguin]

I still don't know why people bother bringing up John Money.

Reimer became schizophrenic because of hormones? It's very peculiar then that his brother was schizophrenic and killed himself before Reimer did despite not being transgender or taking hormones. Also, Reimer got married, but he eventually wound up divorcing shortly after his brother offed himself, and just before he killed himself.

What exactly is the point of the John Money thing aside from he was a guy who bought into some facets of modern gender ideology, and happened to be a creep? Are we pretending that at no point in history did effeminate men dress up and try to live in a socially submissive role, or that eunuchs as servants of royalty is a new thing, and this all exists purely because one random dude came up with it and everyone else decided it was a great idea?
And he advocated for surgery in the case of children being born with genital deformities, he didn't say shit about just deciding you're the wrong gender.

The John Money thing proves nothing. It never has, just at some point dips decided it was some kind of gotcha the trannies don't bring up because it hurts their cause and not because it simply has no pertinence to anything.

But trans identity is innate, it's genetic!

How doesn't what you're saying reinforce that point? Pretending this isn't too messy to glean anything from:

Reimer was born as a male, they were reassigned and ostensibly raised as a female. Despite that fact, when it was later revealed they were a male they got a reconstructed dick and went to living as a male for the remainder of their life until their suicide.
So once again taking this trainwreck as a valid point of discussion and not a complete wash with too many critical variables, he innately knew he was being raised and treated as the wrong gender. So transgenderism is a valid concept.


Trying to "disprove" these people like we're all in a college debate is both ineffectual and kind of a pussy move. The fact is that transgenderism is stupid because it doesn't fucking matter, why is one that obsessed with their gender label and identity overall?
Therein lies the issue, that people need to stop thinking like braindead fucking TERFs who are often as underhanded and/or obsessed with identity as the trannies, and recognize that transexuals are doing what they're doing not because they think it makes sense, but because it meets unaddressed emotional needs that have boiled over due to lifestyle and deeper ills of modern society, or because it opens avenues for social exploitation by making them seem like less of a threat to the status quo.

Just walk right past the tranny shit, it's absurd nonsense not even worth examination and can only obfuscate the actual core issue.

David was given cross sex hormones when he was a child, where did you hear otherwise?

Furthermore hyperfixating on John money alone, which is cherry picking and resorting to ad hominems are exact things troons to use against you. The whole point of still incomplete OP is to prove that troonery is harmful. I wasn't arguing with you. I told typical flawed troon claims you're likely to hear. It's beyond me how you seemed to take this personally

Moreover cross sex hormones decrease sizes of hippocampus, Source people with either schizophrenia or schizo affective disorder have decreased hippocampus. Source David was given hormones while he still was a child.

Reminder that Money claimed that gender is innate and pushed his quackery on a child instead of waiting for proper treatment.

Penis reconstruction was only viable when David was adult decades later, David and his entire family was groomed to believe this pseudo-religious Anti-science bullshit.

Sorry but no pushing harmful gender identity over sex based roles and their function do not validate the tranny ideology.

Whole point of this was to deconstruct their dogma from ground up then focusing on the core issue, proving that transgerism is harmful and was harmful to begin with.

Since I'm on on phone I'll add sources later for hippocampus related material.

 

[Manul Otocolobus]

Other Terms:

LET: Low Effort Tranny - Typically male, has no surgery and takes no hormones. They grow their hair long, wear poorly fitting female clothes, a padded bra, and typically have at least a "5 o'clock shadow" amount of stubble at all times. They're mainly just creeps and sex pests.

TEBR: Trans-Exclusionary Biological Realist - The term for anyone who doesn't believe in tranny bullshit, but is not a radical feminist.

 

[Otterly]

The sex spectrum annoys me. Human sex is binary. A sex is a mating type. Humans have two mating types - one which potentially makes eggs and one which potentially makes sperm. Nobody makes both, nobody switches from one to the other. If you make neither, you’re too old, too young or have a medical disorder or injury. But there are no other human mating types than sperm and eggs.
Anyone saying there’s a spectrum needs to pony up another gamete.

 

[Whatevermancer]

Gender is a nonsense term in psychology

I also used to think this way until I realized that I don't actually grab someone by their genitals or take a blood sample to determine which chromosomes they have, and use a different set of criteria, some of which are not biological in their nature, i.e. hair length, clothes, make-up, etc.

 

[Ser Prize]

Kinsey scale was written from a biased perspective AND founded on bad science.

For the majority of people he polled were in prison.

You can still make out features like the jaw, adams apple, etc to determine sex physically just by looking at someone unless they have actually gone to the length to get every single thing altered. Regardless gender should be considered a separate thing from sex and they shouldn't be conflated, if we are to treat gender as society had seemed to adapt it in the years since Money, but before his original goals of the transgender tie in finally bore fruit. As it's since been further hijacked by the 1,200 genders crowd, it is a further useless descriptor in that context.

 

[Penis Drager]

I agree with a lot of what you said in principle, but scrutiny for scrutiny's sake:

1. Gender is social construct!
Yes you're right gender is a term made up by a quack doctor. Gender is a nonsense term in psychology, there are only two major BIOLOGICAL sexes, male and female with few rare exceptions to this.

Gender and sex have been used interchangeably for hundreds of years. The definition of gender as a social construct is the modern phenomenon. A more technically accurate rebuttal would be that they're basically begging the question ala "I'm right because I defined myself as being right." But even that's not really a good road to go down.
If you can't agree on a working definition, you can't have a sensible argument. It's not really a big deal anyway. Something being a social construct doesn't mean they can be whatever you want them to be. Laws are a social construct. Society's a social construct. Money's a social construct. I can't bend the way these things operate to my whim.
So yeah: It's best to just concede that certain aspects of gender (ie. certain societal norms) are socially constructed but that does not mean society should respect your decision to violate those norms and certainly does not invalidate biological variation between the sexes.

2. But trans identity is innate, it's genetic!
Closest correlation to this are specific genes that are found in homosexuals, there aren't ANY genetic proof that people are driven to attempt change their sex at onset.

Debatable. There are some genes with specific alleles which appear to have this correlation. More research is needed blah blah blah. Source.
Still, even if this correlation holds true, that does not rule it out as a mental disorder. Most of the well known mental disorders have a genetic component.

3. But muh male and female brain
Debunked myth MRIs show male and female brains ONLY differ in size, you get either according to your sex Source chromosomes. If you have abnormalities, that doesn't make transgender ideology any more valid they're rare exceptions

Still a hotly debated topic. And all that's really being looked into in your source is relative sizes of various brain structures. The brain's a complex organ. Size isn't the only relevant factor here.

This is a funny talking point because by definition a female brain cannot exist in a male body. The only way this would be possible, theoretically, would be a literal "brain transplant" where you actually took the brain out of a female and somehow got it into an empty skull intact and working.
