Black And White Comics Another Race Question...why Is It Okay For Black Comics To Often Make Fun Of White People But If A White Comic

Another race question...why is it okay for black comics to often make fun of white people but if a white comic - black and white comics

What would be racist. I've always tried to be cool with all frusterated and I'm not racist I just listen to me all these things time. I saw an ad for a comic strip in the region, a black man and the clip only showed that he said something about white people. I would like opinions of black and white, how do you feel about this?
