The Alt-Right spouts “blood and soil,” white identity, and nationalism. The Antifa is a child of totalitarian tolerance manifested in political correctness and identify politics. While at first blush they might seem radically different, they are in fact fundamentally the same.
They are fundamentally the same because they are both manifestations of materialist politics, and as such they are both antithetical to the liberal (in the old sense of that word) Christian principles set forth in the Declaration of Independence. The Declaration appeals to the inherent dignity of every person created as they are Imago Dei, in the likeness and image of God. At Gettysburg Lincoln insisted that as a people we are dedicated not to a tribe or a sovereign or a place. No, we are defined by a proposition and our system of government is dedicated to that proposition – that all men are created equal.
That proposition can find no purchase in materialist metaphysics. Indeed, the materialist creation myth – Darwinism – mocks the very notion of equality. Whether manifested in the blood and soil right or the smiley-faced fascism of the left, all materialist politics is impelled by the same will to power which gives rise to the same Bellum omnium contra omnes, the war of all against all. The Alt-Right and the Antifa are nothing more than warring tribes in that metaphysical schema.
