Bridget Crawford points to a paper by Stephanie M. Wildman entitled "The Persistence of White Privilege," now available on SSRN. It looks great. I'd also like to point out to any other interested parties that the broader symposium the article was a part of, "Whiteness: Some Critical Perspectives", is available online from the Washington University Journal of Law & Policy.
My seminar paper for my Foundations of Black Political Thought class is going to be on Black views of Whiteness. Any help in finding sources on the subject would be much appreciated.
