I wonder if this would apply to women's changing rooms at the local pools as well?
I wonder how you "prove" you are a transgender person, or if just wearing a dress is all you need.
BTW, this does point out the societal problem with gays and lesbians. You cannot in fact set up a bathroom system that provides "privacy" for them.
Think about it. Suppose you set up a "gay" room. But gays are attracted to each other, so if two go into the room the one might be oggled by the other. It's why we don't let men and women into the same restroom.
But if the gay person goes into the regular men's room, it's like letting women into the room. In fact, you can't have a group with more than a single gay person without that group having the possibility of sexual attraction within the group.
Straight men can shower in a room without fear of sexual attention. Straigh women can shower in a room without fear of sexual attention. You could put a single gay man and a single gay woman together in a shower without sexual attraction. But that's the largest group you can have with gays. Put a single gay man in a room of straight women, and the straight women are attracted to him. Same with a single gay woman. Put two or more gay men together, or two or more gay women together, and there is sexual attraction.
Being gay is simply abnormal from a societal perspective. A gay adult can't be trusted by nature to take either a group of girls, or a group of boys, on a camping trip.
Never in a million years would I be attracted to a gay man. Years ago, when I was a teenager, there was this boy in church that all the girls went gaga over. Not me. I didn't know about the gay lifestyle then, but he just turned me off somehow. Anyway, years later, I found out that he 'came out' and is now living as a homosexual.
