The second thing that happened is, DNA analysis is much more sophisticated. All you have to do now is spit in a test tube and you find out all kind of things in six weeks - where they are from in Africa or Europe. You can prove or disprove the fundamental African-American myth that you descended from a Cherokee great, great grandmother.

The bottom line is that Wanda Sykes has the longest continuously documented family tree of any African-American we have ever researched.

It's no surprise that White people say things when they are together about Black people.

What people forget is that the most radical thing about Obama is that he was the first black man in history to imagine that he could become president, who was able to make other Americans believe it as well. Other than that, he is a centrist, just like I try to be. He's been bridging divisions his whole life.
