Marx replaced what Hegel called God with history. Marx idea that you don't need a God to tell you what's morally right, history will tell you. Neoreactionaries don't like that sentiment that history decides what's morally right.

Speaking of which, let's see what history has to say about Marx. It would appear that the Marxist nations lost to a semi-religious nation. Thus apparently history has judged that the idea that history will tell you what is right to be wrong.
