I'm pretty sure it's broader than this. It's a narrowing range of opinions that are allowed in public discourse. It doesn't change people's minds, it changes what they can and cannot say without risking their careers and public standing. It causes people to internalize their opinions. That leads to resentment and the resentment fosters the intensity of the feelings and pushes people into extremist territory. The extremism will always find the outlet, no matter how hard you try to control it. Think of Gab for example. The site has been described as "extremist friendly" or a "safe haven" for neo-Nazis, white supremacists, and the alt-right. The only reason the site exists in the first place, is that those people were pushed out from Twitter, outside of the realm of "allowed" mainstream opinions. The problem is that by pushing them out, you don't make them disappear, you make them less visible and more radicalised and dangerous.
