Overt? I don't think he believes he's racist. My point was that anyone who is surprised that a group of black people acted "civilized" IS racist.
I don't think that was his reaction though. He was reacting to Juan Williams comment on what many white people think... and O'RLY was simply adding his schtick to it. I don't think he was surprised. He may WANT people to think he was surprised just to up his ratings... but I don't think he was surprised.
