Curtis Yarvin, IIRC in that same avatar of Moldbug, has actively advocated for the morality of slavery. There is no point in reasoning with that, there is literally only war.

Which is kind of a shame, because the top-level article does have some interesting ideas. I hope the author is just young and undiscerning and doesn't actually support the kind of things Yarvin stands for. But also, being a monster doesn't stop anyone from having the occasional interesting idea, so who knows.
