No offense but I think a lot of tech guys on this site have never dealt with the "other side" of life. The other side being the shitty, disgusting, repulsive aspect of humans that occasionally rises to the surface. The reason un-restricted public bathrooms are "challenged" (to use corporate speak) is because the second you have one available, either a homeless person will camp out in it for hours doing everything you can imagine, or someone will be a total anti-social asshole and take a crap ON THE WALLS. I've seen this occur dozens of times, without fail.

Yeah, it isn't as simple as "le humans are bad and mean mmkay." Like most things that remain unsolved, it is complicated.
