It's ok to make jokes about other races because the stand up comedian isn't making fun of the actual people but the STEREOTYPES we all have of those people. It'a an acceptable form of laying out on the table all the stupid prejudices and blanket statments we have about other races/cultures.
Like Chai said back on page one...you KNOW when someone is making fun of the person or if they are simply making a mockery of the stereotype.
