Agree to a large part of this. New Orgs knows upsetting news gets eyeballs, social media platforms elevate conflict above all us to keep users on the platforms, billionaires fund misinformation to keep people distracted and disorganized.
There is a missing step though... and that's the forming of the radicalized communities. People are isolated and fed misinformation as you've said... the solution is to form local community.. but often what happens is people find radicalized communities that justify and encourage violence.
There's a reason that all 3 of Trump's assassination attempts and this car bomb were by Trump supporters - they've found community with a violence-loving radicalized group within the MAGA movement.
The violence is only going to get worse... especially as social services like the VA is cut under DOGE.
