this reply probably doesn't matter since this thread is a few days old, but here goes anyway:

> I encounter professors all the time who think that it’s fine for a student to say “I’m With Her” in class but not for a student to say “Make America Great Again” — that’s hate speech, see — despite the fact that both are simply the recent campaign slogans of the two major political parties.

here's the thing: "Make America Great Again" is a dog-whistle slogan, pining for a time that was racist. it is, to a lot of people (myself included), an inherently racist slogan. so, the problem is that a statement which was "simply the recent campaign [slogan]" of a major political party was, in fact, racist. i know it seems crazy to some people, but one of our major political parties ran an overtly racist candidate, on a (barely) covertly racist platform.

EDIT: sometimes the platform was overtly racist too. though it tried it's best to make it palatable for people who wouldn't want to identify as racist.
