He's talking about the double standards set by blacks, whom passionately oppose anti-black racial slurs yet talk about "crackers" so loosely.
Ho-hum. I know white people who claim to be against racism and yet they still cross the street whenever they're downtown and they see a black guy with a chain coming down the block. These kinds of things happen. People are racist? People have double standards? Oh my God! You've opened my eyes because I never knew that this sort of thing existed!
What's to debate here again?
