P.P.S. Although the "cultural Marxists'" reputation on the modern Voldemort flank is rather more impressive than that of Dumbledore's - certainly a plan to "destroy the Western civilization" sounds rather bold and badass. Unfortunately for the Right, as shown above, such "destruction" and "subversion" are in fact just an ancient, refined and respected tradition of the Western civilization. It suffuses much of our general cultural outlook and gives it a unique character, I'd say - or, some angry and cyncial observers would say, it comes from an underlying feeling of pride, achievement and triumphalism. Only a culture immensely secure in its own dominance and privilege would try such relatively scathing self-criticism. That's oh so human. I'm not perfectly OK with it, but I'd be even less cool with an openly "white nationalist" or "racially realistic", Apartheid-style thinking.
Also. Why e.g. Carlyle should necessarily be ascribed more merit, cultural or otherwise, than e.g. Susan Sontag is beyond me. They were both fairly talented writers with a clear individual voice, and highly elitist. How certain... contrarian elements can say that all fans of the latter are a traitorous degenerate menace to all that is White, while even a communist wouldn't attack the former because Hitler and Goebbels happened to like him... well, it's pathetic.
