I agree that this is an accurate assessment:
“Neoreaction, for me and some others, flows from a bunch of people who were enamored by deontological libertarianism and became disillusioned by some of its more impractical aspects. If Republicans are just Democrats who have been mugged by reality, neoreactionaries tend to be anarcho-capitalists mugged by history.
Neoreaction has three areas of focus: capitalist in economics, traditionalist in its view of religion, and more nationalist/Darwinian in its view of race.”
That this takes a vast amount of anthropology, philosophy and political theory that is fundamentally liberal and skeptic for granted as basically correct. This makes it a subset of the alt-right. This is fine, and it should be formalised and boundries drawn.
