Sure white comics get away with it, george karlen, is a great example, big time! of course he based his making racial jokes on the same stereotypes that black comics do. He was great at it and and blacks or other races couldn't have been too offended, he always filled a room with blacks, whites, indians ect.. way. There are other whites and east indian comics as well, I think they tell the jokes in away that was not offensive to the public. I do think for the most part, black comics tell jokes about blacks that portray how they are truly viewed by society both black society and others. Years before black comics came along there were always stereotypes out there that basically came from the media, which in turn helped racism flourish. The public especially whites didn't believe that there was racism against blacks. So, u c blacks brought these stereotyes of themselves to the stage. Now, you can truly see that there is racism out there.
