Below is what Chairman Ann had to say about the double standard as it pertained to Obama's minister and I think she's right. Per the question at had though, I believe Obama can say "typical white person" for the same reason that one can make a movie called "White Men Can't Jump," but not one called "Black Men Can't Swim." Racism towards white people is considered funny, cute, or richly deserved. While any criticism of blacks makes one a member of the Klan.

As an authentic post-racial American, I will not patronize blacks by pretending Obama's pastor, Rev. Jeremiah Wright, is anything other than a raving racist loon. If a white pastor had said what Rev. Wright said -- not about black people, but literally, the exact same things -- I think we'd notice that he's crazier than Ward Churchill and David Duke's love child. (Indeed, both Churchill and the Rev. Wright referred to the attacks of 9/11 as the chickens coming "home to roost.")
Imagine a white pastor saying: "Racism is the American way. Racism is how this country was founded, and how this country is still run. ... We believe in white supremacy and black inferiority. And believe it more than we believe in God."
Imagine a white pastor calling Condoleezza Rice, "Condoskeezza Rice."
Imagine a white pastor saying: "No, no, no, God damn America -- that's in the Bible for killing innocent people! God damn America for treating our citizens as less than human! God damn America for as long as she acts like she is God and she is supreme!"
We treat blacks like children, constantly talking about their temper tantrums right in front of them with airy phrases about black anger. I will not pat blacks on the head and say, "Isn't that cute?" As a post-racial American, I do not believe "the legacy of slavery" gives black people the right to be permanently ill-mannered.
