I think Curtis Yarvin(And indeed Davis) are not a representative example of any particular idea. Pathologies perhaps, but while the symptoms of such things have enough similarities to identify them, they do not manifest in a way that can characterise a typical expression of the phenomenon. To do so can be dangerous, and result in management of a set of symptoms rather than the cause.
Put into the context of Terry Davis. Terry was not racist because he was Christian, and neither is it true to say that people with schizophrenia will be racist. It was a complex and unique manifestation. I think Curtis Yarvin has a similar level of incomparability
It's a classic Hitler was a vegetarian argument.
