I guess the problem starts when two other cameras are watching the same area the first camera is in.

That’s totally true. I just thought of the possibility because I grew up where not every toilet was civilised.

Not necessarily in the defense of single sex toilets, but I imagine not all men are gentle, and women (maybe even anyone else) would choose not to get peeked at from above by a nasty weirdo. I know, I know, not like only one gender could do it, but if I had to find a reason why one would want to have single sex toilets, this would be the reason that makes the most sense to me.

Or, you know, people being religious fanatics stuck in the 18th century, but who would be like that in 2026? /s
