You see why most Fascists today just stick to relying on shock value by saying the N-word or posting pictures of dead queer people or finding new meme slurs for jews, because when they try and do actually "serious theory" it becomes too obvious how vapid their ideology truly is, although to be fair not many people would immediately even recognise this as fascist because 99% of people only know fascism as "the bad guys in Indiana Jones". Same reason people don't realize how a movie like Metropolis is actually more "orthodox" fascist than Triumph of the Will.
Hell, most people have no idea what fascist class theory actually was because they assume it was the same as marxism for which they also don't know what it is.
