I think this is right but not quite.

Politically, social media lately has fractured into ideological spaces. I go on bluesky or truth social or X or a certain subreddit to keep up with the politics as filtered through my tribe.

A lot of people opt out of these spaces because of the huge amount of political content and the lack of nuance in discussion. But it also radicalizes the people who stay as they get their sides view of the political conflicts of the day. And they get addicted to winning arguments for their side.

It used to be that Twitter revolved around whatever Trump did. Now people go online to find a little club they can kanoodle and bemoan how their side is the ultimate victim. And people will justify a lot of horrible things if they think they’re the victim.
