PAUL adds: As I've written before, the common thread that ties Obama's views to Wright's is black liberation theology, which sees the Christian mission as bringing justice to oppressed people through political activism, and emphasizes the racial aspect of oppression. In effect, it is an amalgam of Christianity, radical left-wing ideology, and black militancy. Obama's autobiography supports my view that, in all likelihood, "only this brand [of Christianity] could [have brought] a left-wing political activist like Obama to Jesus."
The existence of this common threas does not mean that Obama subscribes to the worst of Wright's views, and I'm confident he does not. But I believe it helps explain why Obama found so many of these views merely "controversial," not deplorable.
