Google "Club1" in Savannah Ga. You'll see some pretty famous names from the Trans community, and it's a well-known gay bar and nightclub.
I used to visit the club every Thursday night in the early 2000's for the themed "Goth NIght". The club has 3 floors, and on Thursdays, the main dance floor was always an 80/20 mixture of mostly hetero male and female 18+ art students, and military.
There were no established "Men's" or "Women's" rooms. There were stalls, or urinals. The entire "stalls" bathroom, other than the space inside the stalls, could be seen from the doorway, which was always open. The straight men often used the "stalls" room for the safety of privatized wooden walls. I honestly feel that forcing the men to use the "urinals" room would have been unfair here, as they woudn't have felt comfortable in believeing that every man would be staring at their junk.
I'm straight myself, but I knew going into the bathrooms that someone in there might decide to stare, leer, or even physically flirt and grope me. The ONE time I ever felt that I may be in some kind of danger, it was another woman trying to kiss me, very aggressively. I was inside of a stall, sitting on the toilet with my panties around my knees, she forced the door open, and herself onto me. She was a drunk 30-something, at the time I was 19.
It was a man who stepped in to save me, as he was both strong enough to pull her off without hurting either of us, and he was allowed to enter the unisex restroom. A large man with long hair, a mountain man beard, and decked head to toe in leather Harley gear. He wasn't a bouncer, heck I don't even know if he was gay or straight! He was just a decent human being who tried to help someone in trouble. He called a cab for her, put her into it, and then he bought me a coke to try and help me feel better. I have never seen him since, as he was only a tourist passing through.
Bathroom segregation does not prevent or reduce the likelihood of rape or sexual harassment. Last time I checked, humans cannot see through bathroom stall walls. If you're inside the stall, not only can he not see you, you can't see him, not seeing you. If anyone is going into a bathroom to "get their perv on", they're inside a stall where YOU would have to be the one creepin to know what they are doing behind their closed stall door. The bathroom lobby is still a public area where it's ILLEGAL to "whip it out".
Rape, stalking, and harassment are a conscious choice; those who make that choice will still follow you into single sex bathroom to take what they want from you if they are already that skewed to make the choice to stalk and rape in the first place.
Bathroom segregation does not protect your sense of decency, modesty, respectability, or your moral compass. Your own choices do that. No one has any problems using the single bathroom at the jiffy mart, unless you don't use public facilities, so why do we need a second entirely separate room? I thought we were on a movement towards gender equality.
