That belief isn't unfortunate - technological optimism or what Wired once called "extropianism" is just the same as every other kind of utopian fantasy. And when you're young, and kind, and full of love, and think the world can be fixed if only everyone had the tools and the motivation to express their best selves, it's seductive. And it should be. Because if teenagers and twentysomethings were as cynical and resigned as the rest of us, we'd be doomed. Every generation architects some new utopian paradigm, and has to go through its own process of disillusionment as they watch the mob tear it limb from limb. Ultimately, the best you can hope for is that people learn from history and don't repeat the same mistakes.

That's true, and moot left right before things took their major turn (possibly precipitated by Gamergate, which moot soon banned all discussion of; he left about 6 months later), but 4chan /pol/ is still more extremist than even Stormfront, and nearly as uniform in terms of beliefs. It's not quite as bad as 8chan /pol/, but 8chan /pol/ is as bad as or perhaps even more extreme than Nazi Germany's actual "Der Stürmer", and is where a lot of the far-right mass shooters have posted.

Other boards have varying concentrations of /pol/ injected, with /mu/ ("Music") having a spread of far-left, left-leaning, right-leaning, and far-right posters, and /tv/ ("TV / Movies") and /biz/ ("Business / Finance", but mostly just cryptocurrency gambling/scams) being almost exclusively right-leaning, and mostly far-right.
