Here is my brief experience with such ideology as it appeared on GC.

Some weirdo on there told me that if i didn't give my 2 year old son a special soy diet in order to manipulate his hormone levels, that he would become a rapist. The comment was immediately downvoted by others and someone even replied to chastise the person. I didn't report it, but someone did and within a short period of time the comment had been removed by mods.

In general I keep my interest in men's issues (am wife to a man and mother of a son, and also care about my male students) out of feminist spaces because it ain't that lens' problem and I also understand and respect some women's need for separatism. I think within that sphere there are some real fuckin' weirdos though. Like, who would, especially when we criticize HRT for young people, tell a mother to biohack her child? Reminds me of Jenny McCarthy eschewing vaccinations and claiming diet cured her kid's autism. But from what I see, the real weirdos aren't tolerated. I hope I don't see a rallying cry for women to abort their male children coming from this corner of feminism.
