"Obama not American" believers: are they just racist?

http://www.sfgate.com/cgi-bin/blogs/a... - You know, I'm sick of racists. Just plain tired of em. You know who they are - or maybe they're you. People who are really upset that America elected a black man as president but since they feel they can't say so without the anonymity of the Internet, they craft other means of expressing their anger, like hanging on the to the crazy idea that President Obama's not an American citizen.
