While it's splitting hairs, I would consider a chan site to be social media. It's just not tied to your actual identity unless you want to namefag.
And even if you don't use social media, if you think about it, it applies to any community. It's not like school or work where you have to learn how to deal with someone you don't like or agree with. The Internet lets you silence people who hurt your feelings and stay in your little box where people do not confront you on your views. Chan sites let you filter terms that bug you. Browsers like Firefox have addons like Comment Snub that allow you to completely remove comments so you can't engage people at all. And this is all before we remember that the owners of social media and communities will often limit free speech on top of that.
Now we get people who want people who don't agree with them to unfollow them because of their extreme views. Really, it depends on what kind of friends you have. I don't really have the luxury to be an extremist who ends friendships over politics or ideals and friends and family are more important to me than politics so I live and let live.>>3374
When people who hold more extreme views start getting more control over sites and blogs, etc, it's gonna be harder to learn accurately due to the insane bias.
