I can't remember what it was, but I clearly remember a scene in a movie with a big shower room with individual stalls divided up and it looked like it would work just fine.
The point is, if people have a problem with something, then they can come up with a solution. If it's just bitching with no solution offered or attempted, then what exactly is the point? "Can you believe there is a transgender in the locker room? Outrageous! Well anyways, on to the next thing to bitch about."
The only thing to take home from this is that you can't please all of the people all of the time.
