"...deep seated hatred for white people...and white culture"
I think this one speaks for himself.
Glenn Beck represents the lowest common denominator in American political discord. He is down there with Al Sharpton and the other race-baiters who throw around racially charged comments for nothing more than self gratification and financial gain.
History is full of similar tactics: Think about it...conceptually speaking, this is not a hell of a lot different than the Brown Shirts of 1930's Germany manufacturing Jewish crimes. Beck wants people to believe that President Obama is racist, therefore anything he says (or potentially anything that some nut-bag listener does in response) can then somehow be viewed as a justified reaction.
