I'm one of those people who is really, really touchy about race. I despise racism and do not tolerate racism... which made my stay in south Texas interesting.
That said, I have an honest question about something that's puzzled me for a while:
I know that back before the civil rights movement, one of the many racial slurs used was to call a black person a "spade." So here's the question: The expression, "I'm not afraid to call a spade a spade"... is that a derivative of card playing, is it a racist expression, or is there some other origin for the expression?
