Bannon is a white nationalist. George Will nailed this the other day (!) when he suggested that Trump's America has forsaken Lincoln's vision of a nation bound by and dedicated to a proposition ("That all men are created equal") in favor of a European style ethnonationalism, where a nation is bound by "blood and land," that is by racial and cultural homogeneity.  

You know, it's common in the environmental and peace movements to quote Margaret Mead approvingly, "Never doubt that a small group of dedicated people can change the world. Indeed nothing else ever has." 

But the lesson of 20th-century revolutionary movements is that the "small group of dedicated people" who change history can be intent upon evil and destruction as often as not. Bannon once called himself a "Leninist" and it was Lenin who came up with idea of a small revolutionary vanguard that could reboot history, not Margaret Meade.
