Why does Fox News always have these self hating black republicans on to trash their own culture?

I mean here you have this black republican woman Starr, who comes on here to trash Obama every few weeks, This woman comes on , bashes rap music, trashes black people, talks about how lazy her people are... Need to get off welfare ect, then she talks about her backround. She had 5 abortions. lived on welfare for 16 years, an ex drug addict. Before she woke up to become a Christian Republican. The Tea Party has this guy come out and sing for them named Lloyd, he was on Fox News today and says the first thing he says at his Tea party Concerts is " I'm not an African American, I'm a AMERICAN!!!!" And the crowd loves it, then he talks about how much he hates rap music.... Sitting here dressed like some Rancher... It's always the same, they always have these black people, Black republicans, who hate Obama, come on the Network and they always end up talking this stereotypical Bull**** about black people. Sitting there dressed like some Cowboy or Preaching about how black women need to get it together, even though they have had 5 abortions and are a born again Christian. Becoming Christian doesn't wash you away from your sins. Then you have Herman Cain dressed like Lloyd in cowboy gear 24/7. In order to be accepted by Republicans do they have to first turn their back on their culture, trash and spit on it?
