We can more limited variants of the dark mirror ideology though. For example, we can imagine someone who believes all the tenets of Marxian Communism and uses the analysis to maximize his own advantage, so that he if he is a large property owner ends up doing all the things that Marxists expect large property owners to do-- perhaps he even pushes a liberal ideology in public, but this kind of limited-dark-Marxism in private.

I think the dark liberalism of this essay is a real ideology commonly held by marginal dictators, think Lukashenko. I also don't think this kind of limited-dark-Marxism is unusual.
