>if you go to Reddit or Imgur and other sites, you can see the people from Stormfront, /pol/ and the rest are by no means sitting in those chambers without going "abroad".

Yes but reddit is just a series of echo chambers where dissenting views are rapidly downvoted, hidden and removed by moderators.

I think you're right though. While the ban wave was a turning point for 4chan and image boards. The trend of increasing insularity and xenophobia is seen across all social media and political leanings. Making it too large to pin on any single event on a particular board or website.

I think it's the direct result of having too many choices, so people naturally gravitate toward the communities with the most like minded views and then groupthink dominates.

It's really a shame that instead of opening people up and exposing them to different perspectives the internet has had the opposite effect.
