I don't know if it's 8chan, but there's a really weird cryptofascist--barely even "crypto", tbh--strain in that community. And I can see why. The community that huddles around outdated and bad tech for the reasons they do is going to skew regressive and is going to get progressively (ha!) more upset and resentful over time. That self-selects for the kinds of toxicity that share significant comorbidities with the "alt-right" and worse groups on that axis.
