I feel like most people are wildly inconsistent on this. Fat shaming? Small dick energy? How about mental illness? Baldness for some reason? Disabilities? Oh, we could probably go on about those. Some people seemingly decide a line is too simple and draw a complex sine function instead.
My rule is to try to be decent. Sometimes, I even succeed. But I don't think I'm very good at it, and neither are most of you. Bunch of hypocrites, we are.
