Best friend's friend is a vocal racist

[Gunny Highway]

If you don't like listening to it, just stay away from him. He's a racist idiot, but he can talk how he wants. Just ignore it. My best friend growing up had a big problem with people saying [censored]. It's not a word I ever personally use, but when I'm around him I work it into the conversation just to antagonize him. It's a joke between us, and he knows I don't really think that way or talk that way. But I'm guessing that if you try to change this guy's behavior, that's the reaction you'll get.
