I've seen this said now multiple times in multiple places by what I'm pretty sure are ideologically disjoint groups of people, and I gotta say, it makes me glad I skipped alot of his work. Racism is a hell of a drug. Was just talking with my mom this very morning about the anti italian racism in the early 20th century in the US and the subsequent change in perception of italians (especially southern, which I partially am) as "white". David Roediger wrote an excellent book on this from a labor standpoint, I need to finish it soon......
