I've never knowingly shared a womans space with a trans woman.
I have.
I've never knowingly ever seen a trans woman in a womans toilet.
I have.
I dont know anyone who has.
Depends where you live and whether you know many people.
So maybe this trope that it was just a few transsexuals, but now its different, doesnt actually hold up at all.
Nah. Just because you haven't experienced it doesn't mean other people haven't. Clearly they have. I certainly have.
Anecdotally I'm sure people will have lots of stories for these forums, but every woman knows, her use of womens spaces hasnt really changed.
Although, actually, it has changed.
