To single out a particular group and say we can't make a joke about them is almost a form of prejudice and it's kind of patronizing.
Sacha Baron CohenI think you can be politically incorrect, but there's some responsibility with that. You've got to make sure that you are not condoning or bolstering any racial or other stereotypes. You've got to be free to make jokes, but just make sure...you don't want to go and black face somewhere to just prove a point. If it's insulting and offensive just for the sake of it that's problematic.
