And shit in a restroom is an unpleasant thing to see, but it’s a facility set aside for the explicit purpose of shitting. The explicit purpose of a bus includes transport without shitting. I find it hard to imagine that you can’t conceive of the idea of people being exposed to shit and the types of people who have no issues shitting while on a bus. They’re not mentally stable people and they’re quite possibly dangerous.

And no, we should absolutely not destigmatize shitting on buses or in places other than toilets. It’s not only disgusting to look at, but that’s how you spread deadly diseases. It’s a problem the Romans knew how to handle—let’s not set ourselves back in time 2000 years because some mentally unstable person might be offended.
