I tend to enjoy the banter on 4chan more than here. Everyone is expected to dish it and take it there. Peoples' biases are obvious, because they make it clear who they dislike fairly often. Nobody actually takes any real offense to it all. It's quite pleasant compared to the sanitized world of... literally anywhere else.
Of course, if seeing the N word makes you obsessively clutch pearls, then it's not the place for you. If you can let stuff roll right off you, it's fun, and there can be dialogue of interest here and there. /g/ being most similar to here, of course.
