Personally I find it silly that bathrooms are segregated at all when stalls exist.

You mean the 3-foot particle board separator with a 2-foot gap at the bottom and a solid inch of space around the entire door, the gap large enough to make eye contact with someone at the sink while you're sitting with your pants down?

Because that's what passes for a "stall" in 99% of America. Privacy never even came into the conversation when they designed those damn things. They are designed to give the bare minimum illusion of privacy while still being easily stared through to make sure no one is doing drugs in your bathroom. At any point in time any employee of any company has a right to come into the bathroom, peer through the crack in the door and make sure you're in there dropping a dook properly and not say, shooting up heroin. And you can't stop them even if you wanted to, the stalls are designed to make that possible.

So, with that knowledge, I sort of almost understand the people that get all up in arms about this. Because there is almost NO expectation of privacy in ANY American public bathroom. If we had European style stalls this would never have been a problem in the first place. But because anybody can just walk up and literally make eye contact from outside the stall while you've got your pants down, some folks can be understandably concerned about that.

That doesn't excuse any of this mess and it doesn't make them correct, but non-americans don't realize how shoddy our typical public restroom is. The anger at trans folks should instead be directed at the cheap-ass building contractors that mandate bathrooms that don't give you privacy.

Edit: These are what I'm used to seeing.

If you're tall, your eye level is over the top of that door. If you're a young kid, the bottom of the door doesn't even start until your chest or shoulders. If you're medium height the gap around the door is your peephole, whether you want it to be or not.
