If I'm walking down an American street and anyone darker than a peanut shell approaches, I'll say, "Hello." This because, if I don't say it, he or she might think that I'm anxious. Which, of course, I must be, otherwise I'd walk by in silence, just as I do with my fellow Caucasians.
Does this make me racist, or simply race conscious? Either way, I'm more afraid of conservatives than I am of black people."
