I use the Hippodrome frequently, the queues between performances are really busy, it'll be interesting to see if they're used by anyone wanting a wee fast and folk who are trans. The Hippodrome is located in the, as it has been know for years, "gay village" of Brum. I wonder if they'd have installed it if it wasn't.
A beach resort, here in the uk, I go frequently, has made its loo's all gender neutral and it's vile. If you're queuing for the cubical, you can see the blokes at the urinal, it must be horrible if you have little girls, seeing grown men use the loo. I don't like it myself. It was really badly designed.
Many times in my life, in childhood and my teenage years, did I come across random sex offenders, once being chased in a park through a river (god knows what would have happened if he'd caught me, I was 7), 2 different stalkers in my teens and 2 flashers, one on a bus. If they have this urge to expose themselves and blame it on a design flaw in the toilets, it's easy pray and worries me, to be honest. These people exist.
I have a young adult family member transitioning, who I fully support, so I'm well aware of the situation. I still think public toilets that are a free for all are open to abuse by sex offenders.
