Because transgender and non binary people don't have a place to try clothes on. Everyone should have the right to safe places.
By Jove I think you've got it! A third space!
Except there isn't a single transgender, non-binary person or self entitled man who wants that.
It would be a piece of piss, wouldn't it. An extra space.
But it doesn't happen, they don't want it, no one is campaigning for it, because it's not about the space.
It's about the women in the space.
Transmen aren't clamouring to get into men's changing rooms or loos or prisons, or beating them at sport. They're not making the staff and patients on men only wards feel uncomfortable.
That's not happening. Because it's not about 'identity'.
It's about women, and men wanting to be included in their spaces for validation and/or just to dominate. Which is the same thing.
Do you seriously think there's not a woman here who hasn't suggested a third space? Over and over. It's rejected out of hand.
It's about the women and access to them.
