My full on black friends, are not really close friends with all of my mixed race friends. They know each other, but are not really as close. Only because they are from different area's. I don't use bad language or anything, but one of my mate's is really pale. And he says "N****a" in every other sentence. Its pretty ****ed up to be honest, i have told him before that his language is terrible. I used to train with one full on black guy, and when we where in the gym together.........we used to shout. "There's that Zulu ****, I've been talking about" Its pretty much common sense, and you would know where to draw the line.
