People are people.
The internet doesn’t change nature, just concentrates it.
I commented on a restaurant thread where someone was openly racist in their review, then threw a tantrum and threatened to leave because they were called on it, and other people on the thread defended them and begged them to stay because the regional board needed activity and some of us were being too touchy. (Oh, someone also told me/us to “suck it up” ie STFU, but no, that’s not going to happen.)
So, as I said, people are people.
