Racism and America

My question is based on another question that I just read regarding Oprah Winfrey backing Obama. Some people feel that she is backing him because he is black and that is all. First of all only a few people know whether that is true or false, but I am wondering if Larry King was really behind a politician, which he may be but I don't watch his show or follow politics, and the politician was say, Rudolph Guilliano, would people say that Larry was a racist and sexist which he could be, but people just don't know? Isn't it very possible that Oprah backs Obama who's mother is white you guys know, simply because she thinks that he is the right guy?

Okay, a few minutes ago I was thinking there is no way that this is a 66 year old white guy with this opinion. He's probably a young person that did not want to share who he really is, so he just made up all that stuff, and is just playing around. First of all, on your last answer you said that you don't vote, and now you say you voted fo the big GB both times? No way! One of the negs about the internet. You really don't know if you are messaging the person they say they are. Have a good day, tho:)
