'Because there's no clear-cut answer that doesn't involve some number of male-appearing people in women's spaces. The only issues are 1) how many, and 2) whether they're actually men or biological women who look like men. IME, men who've decided they'd rather use women's spaces than men's spaces (regardless of why), but who nonetheless still look like men, are much more numerous than women who've gone through enough medical procedures that they look like men. Plus, they're not actually men, so don't belong in men's spaces for the same reasons men don't belong in women's spaces.'
Sorry disagree.
Transmen do not want to use female facilities. Undermines identity which is something that feel incredibly strongly about.
Transmen grew up as girls. Into women. They know what it's like. And they will generally not want to unsettle women and girls.
So. They will use the gents if feel confident with that.
Or they will look for a neutral space.
Those who are female are well used to waiting for the toilet, hunting for a toilet, even checking where toilets are etc before going out and doing stuff.
I can't imagine that a transman on T who had the results of T - deeper voice, altered ability to build muscle, double mastectomy, and wore a beard. For example. Would ever want to use the ladies.
And if they did for some reason.
In real life there are still things that women notice and men don't. And you know. We turned a blind eye to transwomen in the ladies for years. When it was not many about, and behaved (IME) in a sort of, very quiet please no one notice me way.
Everything was fine before.
Then sex is irrelevant. To pretty much everything.
When it's relevant you will essentially be referred to as cunts/ breeders and men as men.
Male rapists in women's prisons is fine. So shut up.
Communal changing involving nudity. Naked person with cock and balls out. If a girl notices that's rude. She needs to be educated that naked stranger cock around the place is normal and fine. That it's offensive to think anything else.
Etc etc and so on.
It was fine.
Until the inch given because a million miles demanded.
So no. No way. Get stuffed.
