No, the author is saying that those play into predictable stereotypes of blacks, just like a lot of the unsupported allegations against Sarah Palin play into predictable stereotypes of poor rural whites. Assuming the worst of a person based on their race, ethnicity, sex, or class on the basis of negative stereotypes even when they aren't true is pretty much the core of bigotry.
That is a perfect description of the Obamas and their cadre. Your a genius.
Excellent point. I don't know if I'd go all the way -- "You're a bigot" "No, you're a bigot" conversations are pointless -- but it certainly is stupid and counterproductive to play up all the black stereotypes just because one is talking about someone who happens to be African-American.
