NanKate
Just as an aside. Yesterday I went to the public loos. Just before I entered a man went in so I waited outside for him to exit. Now it could be that he used the Ladies as the Gents was boarded up but I wasn’t going to risk it.
That's what we have all been taught to do from childhood, NanKate. We trust our instincts and know that men in a Ladies' loo are best avoided. Even if they have good reason to be there, we assume otherwise until we find out - it's self-preservation. We also instinctively suspect people who are 'not as they seem'.
Asking women to forget all of this info - to call men 'she', to pretend not to notice an obviously male body in a dress, to agree that women is a class that can contain all-comers, so basically doesn't exist - is gaslighting, and dangerous to children and young people, who |(if this continues) may never learn fairly basic survival skills.
