The "hurtful speech" Stasi at Missouri U

So when the student body president was walking along, and a truck full of students slowed down to hurl the n-word at him (not the first time this had happened to him), you don’t see that as hostile, harassing, and racist?

Who’s in the wrong here? Why do we place the onus on black students to just stop being so sensitive already? Why can’t white racist students be expected to behave like semi-decent human beings? That’s asking too much?
