Godwin's Law stopped applying when the internet became overrun with literal Nazis. Don't let them use that shit as cover.

Mike Godwin: “By all means, compare these shitheads to the Nazis”

But also, the qualification of certain types of art as “degenerate” is a symptom of second feature of Ur-Fascism, “traditionalism.”

Traditionalism implies the rejection of modernism. Both Fascists and Nazis worshiped technology, while traditionalist thinkers usually reject it as a negation of traditional spiritual values. However, even though Nazism was proud of its industrial achievements, its praise of modernism was only the surface of an ideology based upon Blood and Earth (Blut und Boden). The rejection of the modern world was disguised as a rebuttal of the capitalistic way of life, but it mainly concerned the rejection of the Spirit of 1789 (and of 1776, of course). The Enlightenment, the Age of Reason, is seen as the beginning of modern depravity. In this sense Ur-Fascism can be defined as irrationalism.
