This is the kind of "common sense" thing that sounds good, seems simple, and that most people would agree on - which is the appeal of people offering easy answers, I guess. So who decides what language is simply "not polite" and what is offensive? Is calling someone the N or C word merely "impolite"? Do "normal" people never engage in anti-social conduct? (I'd label most Trump events as "anti-social", based on calls to "own", "kill", "destroy", "lock-up" political opponents, etc.) At what point does anti-social behavior preclude participation in the broader society?

Sorry. I'm just sick of the "it's simple common sense" crowd this afternoon....
