I think there is more as regards Communism. Not only is there Karl Marx's economic Communism (theory of surplus value), but there is also cultural Communism, to use William Lind's description, or kitsch Communism to use David Horowitz's description; e.g., so-called political correctness.
PC is a form of Communism. Gramsci wanted to destroy the culture or Communism would never take root in western Europe or the U.S.
David Horowitz refers to PC a kitsch Communism because it is just so ridiculous or unimanginable. At least Marx's view of a classless society is imaginable, but a raceless, sexless (in terms of sex differences) society is ridiculous. PC is a further degraded form of Communism and one can taunt un American types as Communist because they probably regard America as imperialistic in keeping with Lenin's work of imperialism being another wretched stage of Capitalism.
David Brudnoy was known as a libertarian, and generally on the conservative side of libertarianism, although he often went off the reservation on one political issue or another.
May I disagree a little? I'd say instead that it's the Frankfurt School rolling around in the mud and brawling, trying to reduce everything to ashes in their best "Disco Inferno" style.
Of course, their argument that all the bourgeois organs and institutions need to be destroyed down to the last brick so that tabula rasa Communism can arise unsullied from the foul ashes, is a huge lie, since they had before them even when they generated that pap, the example of the Russian Bolsheviks of 1917, who did no such thing after they stormed the Winter Palace but simply renamed the state ministries in an attempt to get other people THINK DIFFERENTLY about them after they came under Communist control.
So much for "burn that mother down!"
