I agree that there is a hardcore anti-trans culture on MN and it's odious. They argue gender is a purely social construct - fluid and bearing no relation whatsoever to biology. Then they explode into paranoia and bigotry at the prospect of a minuscule percentage of men who may potentially take this concept of "gender fluidity" to its extreme.
@g1tterati , with respect, you do seem to be confused about the position of feminists on this issue. Trans ideology is the one that says that gender bears no relation whatsoever to biology, and can be fluid. Also that a sense of 'gender identity' is innate, and determined by personality / interests. So a boy who likes fairies or a girl who likes cars might really be a girl with a penis and a boy with a vagina, respectively, because personality aka gender identity is what determines if you're a boy or a girl. To think that sex organs have anything to do with being male or female makes you a vagina fetishist, or penis- obsessed.
The feminist position is that it's our biological sex that makes us male or female, and all that other stuff - beliefs about what roles men or women should play in society, what toys kids should play depending on whether they're boys or girls, what interests and aptitudes men should have as opposed to those for women - those rules (aka gender) are culturally imposed, not innate, and the goal should be to break those barriers.
The reason this difference of opinion on what gender is, and whether it's biology or an internal feeling / personality traits that define womanhood, matters so much right now is that changes to the law have been proposed which would mean that 'women' would no longer mean, in law, that class of people who share female reproductive biology. It would mean 'anyone who says they're a woman.' Which means 'women-only' anything would cease to exist, because 'women' no longer has any meaningful definition. Sports, hospital wards, refuges, women's programmes in STEM and politics...
The idea that our sex determines our personality is pretty regressive and antifeminist, isn't it? Yet the idea that our personality determines our sex is somehow lauded as progressive, even though both declarations ultimately say the same thing: boys and men should be like this, girls and women should be like that. That sexist garbage is about to be enshrined in law.
So yes, the feminists are talking.
