“And exactly how many pass? Almost none.”

I don’t know. Nor do you. Largely because trans women who pass, by definition, aren’t read as trans women.

Yes, very obviously trans women are not women. But if a trans woman passes as a woman, then there are certain situations where them living as they please is based on YOUR perception.

There’s a good chance, for example that you’ve passed a trans woman on the street, or even shared a bathroom with one, and felt zero discomfort because you perceived them as a woman. So, and this is a serious question, what do you suggest doing with this person?

I’ve been unequivocal in my support for women’s spaces. And, of course, spaces like prisons and rape shelters and sports are different and should be managed based on sex regardless of presentation. But total absolutism seems silly as well as obviously unenforceable.
