Yeah, okay, I know that using the word that way doesn't necessarily mean you hate gays. What it does mean, though, is that you don't give a damn. About the feelings of others. About civil rights. About anything but your own stupid lazy self.
No, I don't want to censor anybody. My purpose is not to say "You're not allowed to use the word in that fashion," but rather to say "Don't you realize how rude that is?" And if you can't at least respect that, then what the hell kind of friend are you?
