Turned out to be left-leaning, ultimately.
Gun nut with a trans-baddie gf who decided to shoot up a school event out of a toxically masculine sense of righteous pride? How is that left-leaning?
Sometimes I think people work really hard to put this or that fringe figure somewhere on the Left/Right divide, when this guy was just armed, online, and easily ahem triggered. You could say the same thing about Luigi Mangione or Thomas Matthew Crooks. None of them fit neatly into a partisan bucket. The plurality of Americans don't fit neatly.
Unlike with Charlie, this shot went over my head.
