Toxic nerd fandoms do not directly map onto the far-right. Sure, there's overlap, but not all of them share those politics or are even political. There's also plenty of people who'd tar, feather, and run someone out of town on a rail for not being woke enough. Or who just have meltdowns about how the minute something isn't quite the way they wanted it, it's "TOTALLY RUINED!!"

Some small fraction of all of these weirdos would be willing to call in a death threat or actually follow through.
