I would just add that there is a third "aspect" or "color" to this stuff besides "this is the most absurd irony" and "we definitely believe this hatefully bs". That aspect is "we don't necessarily believe this stuff but look, we've discovered dynamite in a bottle." It's something like "trollocracy" - "by believing anything and saying anything, we're amazing influential and we can use that influence in a calculated way."

But that third attitude isn't something distinct from original fascism. One might say the ideas of fascists from the start involved something like "use your illusions".
