Yup, and I don't know the solution here, but I'm honestly giving it a solid try. I intentionally place myself in online groups where people disagree with me to hopefully learn something from them and challenge their own preconceptions. I'm working on a ranking algorithm that should help highlight insightful content based on a web of trust (trick is to trust people who vote based on constructiveness, not agreement).

People point to media companies and politicians for the reason we're so divided these days, but really that finger should be pointed back at us, the people. Those politicians wouldn't be in power and media companies wouldn't optimize for divergent opinions if we vote them in and reward them.

I don't know the solution here, but I try to do my part. I live in a very conservative area, have libertarian views, and spend my time on leftist social media. I just hope it all balances out in the end.
