From his column in today's New York Times:
... would it be totally annoying to point out that the whole White Messiah fable, especially as Cameron applies it, is kind of offensive?
It rests on the stereotype that white people are rationalist and technocratic while colonial victims are spiritual and athletic. It rests on the assumption that nonwhites need the White Messiah to lead their crusades. It rests on the assumption that illiteracy is the path to grace. It also creates a sort of two-edged cultural imperialism. Natives can either have their history shaped by cruel imperialists or benevolent ones, but either way, they are going to be supporting actors in our journey to self-admiration.
