No, they don't, and unfortunately, it's implied. I didn't make the rules, and I don't comply to them.. I refer to myself as a "Cracker", I actually find it humorous, but I am sure that some wouuld be offended by it.
Some white people would find it offensive to hear Bernie Mac call Matt Damon a "Cracker-ass-cracker" in "Ocean's Eleven", but I find it hilarious. Yes, I am a cracker. Also, I am a gringo. I'm sure I have many other names in other cultures, and I embrace them all. I am all of those. I don't mean it in sarcastic terms, no matter what anyone thinks.
