My thesis on why Nazis are attracted to K-On is that low-stakes CGDCT can unintentionally serve as aestheticization of politics.

Fascism attempts to organize the newly proletarianized masses without affecting the property structure which the masses strive to eliminate.

This is opposed to “politicization of art” i.e. “art is ultimately subordinate to political life and thus a result of it, separate from it, but which is attempted to be incorporated for political use as theory relating to the consequential political nature of art”, like how art is utilized in Communist societies.
