As a disinterested (in both senses of the word) outside observer, I'd point out that while his (c) is pretty much the same as (b), sans the editorializing it's in no way incompatible with any of the previously mentioned Yarvin/Moldbug quotes.
Take, for example, the statement "America is richer than Mexico." By which is meant, "on average, Americans are richer than Mexicans." Someone else could say: "But there are plenty of homeless people in America, and Carlos Slim is the richest man in the world! There are vastly greater internal differences in wealth within America and Mexico than the difference between the two countries' averages."
Perfectly true. But, it doesn't then logically follow that America and Mexico must not differ in terms of average wealth, or that the difference in average wealth between the two countries is irrelevant or less relevant than their internal inequality.
"Racist" is essentially a term of abuse which no group or party has ever applied to itself.
To be a little pedantic, that's not strictly true; as Frost points out, "racist" was originally intended as a literal translation of the German völkisch, which the Nazi Party certainly self-described as. But I suppose you could say that's the exception which proves the rule.
Apologies if I've made you feel old!
