I'll switch gears for a minute and agree with Ong about the definition of racism being diluted.

You'll have a hard time convincing me that the movie "Blazing Saddles" is racist. The dialogue is accurate for the time depicted. The racist sentiments are all expressed by characters portrayed as buffoons and simpletons. The most adept and charismatic character in the movie is a black guy. And yet, you will NEVER see that shit on cable TV ever again. It used to be on all the time!!
