I am the offender, I guess. What can I say? I'm old. I remember when such expressions were not meant as racial slurs, but in reference to the characters in the Uncle Remus stories (specifically Br'er Rabbit). In that context, I used it to refer to a nemesis which is difficult to discard, and not in some racist fashion.
But I got negative reps, and a scolding from the Mod, all because someone applied politically correct false outrage to the characterizations of someone who was young when their parents were not yet born. In short, I got gotcha'ed. That sort of thing passes for ethical vindication these days.
Maybe ths whole thread should be subsumed into the PC conversation.
