I don't think that the white-trash in question had any concept of PC. In fact, he was surprised that I was shocked at his expression. I'm not sure the guy had ever even spoken to a real live black person, despite the fact that there were many in our neighborhood, and most of them were pretty darn nice, too.
But my point wasn't really racist comments, it was just weird ones. Cat's gotta dance? Where's that come from? What's it mean? I'm still trying to figure out "dooger," myself.
