This is the result of the attention economy and the fact that nothing generates engagement like anger. That's what gets the most clicks and does so much cheaper than real journalism. So performative outrage is what becomes incentivized, both in the news and on twitter in a self-reinforcing cycle. Those who generate and harness the most outrage are the winners of the game.

How do we fix this?

That's an open question. But I think we need to change the game and the incentives. We probably need a new business model and/or for this kind of news to become widely understood as the junk food entertainment it is. Maybe put a nutrition label or cancer-like warning on them, heh...
