He is noticing something that is true but because he's low IQ and a tv brain completely trapped within liberalism he has a totally retarded understanding of what he's noticing.

What he has really noticed is that materialists, of which all leftism is, have no sense of transcendence and thus they are incapable of producing art. This of course includes what he calls the right wing or conservatives, which are just leftists IE they're rooted in materialism and individualism.

The problem with his framing of it is that he thinks that the 'left wing' of leftism IE marxism, left-liberalism, anarchism etc somehow are the segment that represent art. It doesn't take a genius to understand that this is patently false, take a look at any realm that you would consider a part of high culture: painting, music, architecture, sculpture, philosophy, poetry, literature etc. Which of these has its greats being liberals, marxists, anarchists? None of them. In fact you can literally just look at the art produced in the Third Reich alone and it towers above the entirety of leftist Culture that has ever existed, effortlessly.

Everything that is truly spectacular is transcendent, it represents the Good, the True, and the Beautiful. The actual right have a monopoly on these concepts as materialists simply don't believe that they exist. All greatness has come out of spiritual men, in the modern era they've all been reactionaries or fascists, in the pre-modern era they represented what everyone believed.
