Seems to me a simple concept.
Separate toilets, men go into the men's and women go into the "ladies."
The transvestites go into the toilet associated with the appropriate dress.......
It depends how you define a "woman?" or "lady" and how one associates their surroundings.
Toilets are smelly places, consisting of the smell of urine and faeces and unsavory sounds which would put me off, my idea of a woman.
The same for a woman...surely the above mentioned smells would "put me off" women.
Men smelling badly in a male dominated area is just.....just.....acceptable, but women smelling badly in an area other than wholly female is totally unacceptable.
If the NJ is happy to go into a communal toilet, smelling of urine and ***, seeing a woman coming out of the toilet with the cistern flushing........good luck to him........but i am not.
As for trans genders? I couldn't care less as they are in the minority, but might i suggest that they go into whichever they feel happier in.
Keep the toilets separate.
