Like previously mentioned, CAIS is a separate medical issue that really does produce XY women that, while they have male gonads inside them... are phenotypically hyperfeminine. Seeing some people say that XY is male and XX is female and that's that, case closed, like you do so often from various people leaning to the right totally misunderstands the messy biology behind embryonic sex differentiation. CAIS individuals despite their internal gonads have few obvious indications they are chromosomally male and treating a CAIS individual as male is just something someone would argue for if they couldn't admit how utterly wrong they were on the subject (not necessarily you, but others on KF).
This also has consequences for the right wing postulating that transgenderism is a metal illness that should be treated as such. The problem is, if transgenderism is a result of development after wonky hormonal shit goes down or whatever, their brain structures, possibly, may have permanently developed this way. So if (true) transgenderism is indeed a true biological phenomenon then there's nothing that can be done but accept them as they are.
First bit : I think it is narrow minded to say that everyone who question transgender phenomenon as rightoid,... I mean, I do understand that narrow minded right wing views can look like.. but I don't think 'all
I found your view interesting and you feel like you know what you're talking about... but I don't think I can completely agree with it, and I can get your point that there might be biological reason why 'transgenderism' is not just a 'mental illness' due to whatever the wonkiness that goes in and that there brains structure may be masculinised or feminimised in the way that is different from the norm... the thing is, Would that kind of brain changes really make someone 'trans', or simply it is our culture that let it happen?
And when I say trans, I specify modern, 1st world construct of being trans where they should be treated exactly as the opposite sex. Yes, there are people who want to present as opposite sex throughout the history - but that is not the indication that 'transitioning in modern, 1st world sense' is a correct path to deal with it.
You may have seen the studies that homosexual people actually do have sex-atypical development for the brain - but what makes someone truly dysphoric/trans seemed to be based on body mapping related functions... which isn't particularly gender related, the same feature can be presented as other kind of body dysmorphia - so this is where I believe environment comes to play. I'm actually from a country where 'transitioning' is high, but people there don't see 'what would be MtFs in the west', as truly like female people, but rather their own social category of third gender and the reality of them being male is still acknowledged... so they are not really trans, don't you think? If they have dysphoria, it would present entirely different from westerners and yet I don't think I can really compare their brains... but it made me think that while gender non-conformity might be biological, 'transgender identity' is cultural.
What if we managed to find a brain function that may indicate inclination of someone to be trans, but there are also 'gender non-conforming' population who have the same brain difference but do not want to transition.. how would we even decide with this from physical standpoint alone?
Also I kind of disagree with you about CAIS, and my opinions probably lies closer to
Malevolent Grimace, Of course, there have been people who lived, loved, and died throughout history not knowing that they actually had male part. And then throughout the history there have been people who believed giant throwing hammers from the sky caused thunder before we understood electricity. - Well, treating them as 'male' in the close-minded rightoid argument that XY = male and XX = female doesn't make a lot of sense, but there are significant physical differences they have that would not match perfectly female person either because there are a lot of development that are dependent from SRY-based blueprint but not as related to hormones (skull size and body proportion seem to be one), and we may eventually learn and discover more of it... so i don't think it's correct to say that they're identical to normal female either, even if they may appear similar to one externally.
It's certainly a thought-provoking condition - but may I ask, can we just see them as 'their own being' with all the physiological messiness that came with it, or do we need to put them strictly male/female box? It's not necessarily rightoid mindset I'm talking here, but the idea that someone has to be defined through standardised term (even though the term keep getting muddy)... is a common process in both left wing and right wing by people coming from Protestant-dominated culture. The need for thing to be pure and perfect, fitting into their mental category seems to be a bigger culprit. Can't there be a 'multiple level' of understanding reality and acknowledgement, can't there be thought-improvisation when something doesn't fit into our standard - can someone be a woman in one sense and not in another?

@Malevolent Grimace said again.. "It's actually the birth of modern rationalist science, along with things like eugenics, that got people in interested in classifying mental disorders and pathologized a whole ton of things that people just accepted previously".. and I feel like rationalism and enlightenment can feel like a secular version of protestantism
