Oh, and one of his neophyte followers got cold feet before dying in suspicious circumstances, to which LaRouche naturally responded by claiming that it was a hoax launched by Dick Cheney to undermine his otherwise-sterling reputation. And before you ask, yes, of course he had his own compound maintained by loyal followers and armed guards.
So LaRouche was ... let's say a bit of an odd duck. Now stop us if this sounds familiar: A political outsider claims that America is teetering on the brink of destruction, and that only he can restore Western civilization to some vaguely defined glory days. His ideas aren't crazy or wildly impractical; they're bold, too bold for the stodgy political establishment.
Sure, he's a belligerent manchild who says awful things about anyone who ever disagrees with him, and some of his ideas seem contradictory, and anti-Semites really seem to like him for some reason. But that's because he's a next-level genius trying to save a doomed society by taking those stuffy elites down a notch. The fact that his ideas are barely comprehensible is clear proof that he's smarter than the rest of us. So are you with him and his plan to give power and jobs back to the people, or have you been brainwashed into hating America by his endless enemies and the lies of the mainstream media?
LaRouche is far from a perfect analogy for Trump, if only because LaRouche had bizarre but passionate opinions on why Plato ruled but Aristotle drooled, while if you were to ask Trump for his thoughts, he'd tell you that Plato has always been his favorite Disney character, but he could tell that Aristotle was a bum from the moment he met him. But LaRouche and his followers helped build a world where Trump could thrive. A world where Alex Jones could become a celebrity and the alt-right movement could spring up, all because we accept that a certain level of violent, factually dubious ramblings will always be buzzing away in the background.
