I wonder, has the New York Times ever described any political movement or ideology as "extreme left," or condemned racial/ethnic identity movements among non-whites?
I think their taxonomy works something like this: White, western nations who want to preserve their cultural identity (or just survive) = "right wing extremists." Non-white, non-western peoples who want to preserve their identity (in their own nations and as squatters in western nations) are mainstream and praiseworthy.
