Fair question. It seems to me that language isn't ever intrinsically hateful; what's hateful is the intent with which humans sometimes use it. "Nigger" isn't hateful when Chris Rock uses it; arguably not when Mark Twain put it in Huck Finn either. That's one of the fascinating things about language: the minute you try to pin it down, new usages appear that escape your grasp. Often to comedic effect.
