Male "rights" are a fucking joke.
Half of your complaints are about things men do to each other which you bizarrely scapegoat women for (male on male violence, refusing to talk about mental health issues, circumcision - which is a male invented practice that is nothing like FGM unless the entire head of the penis has been removed); the other half of your complaints (not being allowed to own women like property, or to stop your daughters from getting a higher education, or marrying underage girls, or being able to punish disobedient wives etc) are not oppressive to men at all.
FGM and MGM are both ethically horrendous, and no amount of "one is worse than the other" matters, when both require a gross invasion of physical autonomy. The origin of either practice is irrelevant, and it solves exactly zero problems that can't be addressed by good hygienic practices, and in the rare case of phimosis, with a non-surgical device and steroidal creams.
The rest of that reads like something you read on a chan board, although I'm sure I could also find something similar in Molyneux's ravings, and no one should take him seriously.
As for child custody, it is determined by who the main carers are, if they're fit parents and the circumstances behind the marriage breakdown (alcohol and/or substance abuse, domestic violence or coercive behaviour, extramarital affair etc). THAT IS FAIR, whether misogynists like it or not.
It is NOT "oppressive" to men that mothers are given equal opportunity to fight for custody of their children - something which was once denied to mothers for centuries.
However, if misogynists are going to operate under the moronic "logic" that - despite the 24/7 breastfeeding and childcare (while coping with the vaginal stitches, post natal depression, mastitis) on top of the housework and, for some women, a job too - women have absolutely "no right to custody" of the children they grew "just because" they gave birth to them (not forgetting the women who endured excruciating miscarriages, stillbirths and IVF) then misogynists need to explain why they have a right to custody just because they briefly inserted their penis into a woman's vagina and ejaculated...which is no different to the mother supplying her eggs and uterus and is certainly not on an equal footing with pregnancy, life-risking agonising childbirth (and living with the subsequent health issues) or 24/7 breastfeeding etc.
Modern child custody is predicated on the "Tender Years Doctrine", which assumed that women were better at raising small children; prior to that, men were awarded custody because they were legally responsible for all of the costs of the children, like apprenticeships, school, etc.
If a father is part of a child's life, then you're doing all parties a huge disservice by declaring that women be forced into the role of primary caregiver, just based on the laundry list of negatives that stem from fatherless homes and children subject to parental alienation. Some of the big downsides are lowered educational attainment, lowered economic success, higher rates of criminality, substance abuse, psychological issues, and early single parenthood.
The more MRAs, MGTOW and other misogynistic morons scapegoat and vilify women because they can't take responsibility for their poor decisions, behaviour or sexual failings; the more they prove to women that they are not worth the suffering of childbirth or wasting the best years of their lives raising them.
Which is exactly why the scapegoating, vilification and hatred of women and mothers was pushed onto White men in the first place who are too thick to realise that they have guaranteed their eventual annihilation...exactly as intended.
Mediocre radfem bait-posting in that last paragraph.
I mean, there's good bones here, but:
The problem with MGTOW isn't that they are fighting for men's rights. Good men's lib activists fight for the same things good feminists do (or any egalitarian would): equal pay, less restrictive gender roles, parental leave, more equal parenting roles, freedom of emotional/sexual expression, abolishing the draft, more male birth control options, etc. No reasonable person is bashing MGTOW for wanting these things.
The reason they are terrible is because they blame women for all of these societal issues. And the root of it isn't even their disdain for these issues, the root is that they hate women because they can't get laid. And they take it further than equality, which you touched on, wanting to go back to the ages where women had no rights. Because they actually might be able to get laid then.
The issue is that MGTOWs aren't the ones agitating for any of those changes, they're the ones standing off to the side screaming about how lame it is to have relationships, while doing less than nothing. Whether MRAs are accomplishing anything is clearly up for debate, but feminists are rarely in favour of any significant reform to any of the actual issues, based on the number of times NoW has lobbied against shared parenting legislation, or refused to admit that there's something close to 50 years of empirical data that shows that domestic abuse isn't the gendered issue they present it as.
In my experience, the overwhelming majority of MGTOWs are pretty much the same as obnoxious political lesbians - lots of ill-informed yowling and attention-seeking, not especially much accomplishment.
I mean, you could also argue that it's more dangerous for women because of the rates of
rape and
domestic violence (not trying to imply that there aren't male victims of these things, btw, it's just that women are statistically more likely to experience it).
I've seen CDC material that shows that men "forced to penetrate" happens at similar rates to women forcibly raped, and there's like 50 years of studies showing that bidirectional domestic abuse exhibits gender parity in victimization, and that unidirectional abuse is 70% initiated by women, so I'm going to have to hit X to doubt.
