not just the blanket “but they are menz and I might get raped”**
what’s wrong with this? It’s true and it’s the reason separate spaces for women exist - along with the increased risk of murder, assault, harassment, intimidation, leering, flashing etc. it literally is the reason - alongside privacy and religious beliefs etc, but it’s the most important reason.
when we’re talking about women’s safety generally, aside from the trans issue, everyone understands this. Protection for women in the form of singe sex toilets, hospital wards, prisons etc is there to save women from the vastly higher likelihood of being raped and similar, if men are there.
add to that that we know trans-identifying men are MORE likely to be sex offenders than the average man. That doesn’t mean they all are, of course not. It means more of them are than the background level of men who are not allowed into women’s spaces.
that’s not surprising at all when self-Id policies mean any man can say he’s a woman and get access to women’s spaces. Who wants that? Sex offenders. And saying you’re a woman gets male offenders access to women’s prisons. Who wants that - sex offenders. And we know many TW, even if they are not deliberately lying just to get access, have a fetish about being in women’s spaces and find it a turn-on - many openly say so themselves.
so the reason for women’s safe single-sex spaces becomes even more pressing when it’s TW we don’t want there, not less. And that reason is sexual assault and flashing (and btw flashing is known typical precursor to more serious sex crimes).
