The radicalization isn't going to stop. At some point, institutions have to decide whether they're going to keep playing the game with "both sides"-isms or simply refuse to hand platforms to white supremacists and quasi fascists. This has never been about censorship. There are plenty of right wing "thinkers" who can speak on campus or write an op-ed. Freedom doesn't die because Milo/Bannon/etc can't speak on campus, or because an editor decides that running a pro-fascism piece isn't a good look.
But back to the radicalization. Ben Shapiro spent nearly a decade making overly racist comments during the Obama years. Today, the fact that he's not completely on Trump's dick has apparently earned him a spot at the big boy Serious Table. When you keep moving right and your opponent doesn't change the game, you move the center to the right too.
