How exactly are they unsanity disasters? I would much rather use a urinal and never need to touch anything (besides myself, which unless I myself am unsanitary that should be clean) than need to either sit down and make contact with a surface a bunch of other people have made contact with or need to lift down and raise a lid to use that if I am standing.

Looking online I can't find anything about how they are any less sanitary than just a public bathroom is to begin with.

Unsightly, maybe, but I don't see how they're unsanitary. Urine is nearly sterile.

If you're standing up, it's also a lot easier to "hit the target" into a urinal vs. a toilet. Having a bunch of people peeing standing up into normal toilets would be a lot more gross than urinals.

Men peeing into toilets always results in urine sprayed all over everything. I don't see how urinals could be worse.
