Word that offends black people, if you are white.
white person: "The colored girl, not the white one".
black person: "Are you calling me a slave?"
white person: "No."
black person: "Well, you said the word colored and that word is what you all use to describe us as you are hanging us."
white person: "umm, I was trying to be respectful".
black person: "Well, you are a cracker."
--and this is ok, apparently.
