I basically agree, but I think we should also think about this in a solution-oriented way at a large scale, beyond just personally opening one's own eyes.
Tribalism is part of our nature. It's not necessarily a bad thing, and it's fun. It makes us feel good to belong. The sports analogy is frequently brought up and is the example of tribalism being leveraged for entertainment and social bonding. It's a clever way to us to short-circuit our instinct for tribal warfare and use it for something constructive and fun instead of destructive and tragic.
Politicians and media outlets have started using this insidiously for their own powergames. Maybe this is too cynical, but it seems to me that the circus has been poisoned. You hear about all these people who "aren't into politics" but will repeat their CNN and Fox soundbytes. There's nothing terribly wrong with being personally apathetic about politics, in fact that's the norm for those people currently benefitting the most from existing policy, but it's terribly dishonest and destructive to lure such people into the political arena when they have no sincere interest in the impact of their political decisions, but a few powerful people benefit and countless powerless people suffer.
How do we reclaim our circus? Do we really just need more ESPN and less CNN? Can we punish politicians and news sources for the pervasion and perversion of information as infotainment? Can we educate people to source their identity from their family and culture instead of from their senator?
