What political liberals like me actually think is free and open discourse is bad for lumpenproletariat plebs, but good for highly-educated, refined, cultured, intelligent people like me. Autist Scott either didn't pick up on this "elephant in the room" (to borrow Robin Hanson's phrase) or didn't agree with it, but didn't want to debate it either. Some of my fellow liberals didn't like this and thought they'd engage in a little freelance denazification.
This was always going to happen at some point. Scott oughtta either kept it hidden, kept his liberalism hidden (we liberals really hate when someone on our side does this kind of shit), or manned up and argued for why it was OK, even though theoretically plebs could see and interact with this shit. He did none of these things, autist that he is, just trying to pass himself off as normie while literally linking to neoreactionaries in his blogroll (good luck with that, Scott). Which is a bit like that psychopath that appeared on TV once in a ridiculous mask that failed to conceal her identity.
