Like it's so frustrating to talk about issues like this on HN because huge swaths of the US part of crowd see themselves as very distant from the "gods & guns" crowd but then fall into the same patterns of thinking that hate and extremism are just part of this world and that the free market (of ideas) will solve everything with proper education and personal responsibility. That any solution that isn't perfect or has a downside for them personally is worthless because they're so insulated from the actual harm being done.
That's all fine and good in a world where everyone is acting in good faith, truthfully, and that propaganda, and emotional manipulation don't exist. But the internet isn't some some big Socratic circle.
The people in the comments here haven't had their online life improved by a huge subreddit ban, forumn takedown, or twitterspehere implosion after having exactly zero power to do anything other than endure the abuse and hope to not catch their eye and it shows.
I mean, sure, it’s nice if it isn’t in your face all the time. I’m glad Google’s SafeSearch exists. But keeping people who are actually curious from finding things is much harder than that, and there are a lot of curious teenagers.
This isn't even specific to extremist views or even politics in general; in all parts of life, from the foods people eat, to the religion they practice, to the music they enjoy: people will consider "normal" that which they constantly perceive.
