It's a funny thing about racism. I know some people who are openly and unapoligetically racist, who, nevertheless, like certain people who belong to the races they don't approve of.
One guy I know genuinely believes, and he will tell you that he believes this, that people with blond hair and blue eyes are genetically superior to everyone else. But he thinks Colin Powell is a great man. But he will also tell you that Powell has a lot of "white" genes in him, too, and it's those genes that are responsible for his greatness.
I noticed that Rush's site makes fun of Al Sharpton for pronouncing the word "ask" as "aks". That's something I've heard a lot of racists do.
