I would pay cash for access to a social site that bans all US politics, the astroturfing associated with it is simply unbearable.
Wouldn't that be almost impossible?. Politics affects our lives every day. Your comment suggests that you believe it doesn't affect yours. https://en.wikipedia.org/wiki/Empathy
The vast majority of people do not want to get on a forum to escape their life to see every more or worse content about their daily lives.
You're right, there needs to be some outlet but when people propose this it's because they are sick and tired of politics and the injection of them into everthing is not helping those politics, it just makes it worse.
Tons of people aren't political creatures and want nothing to do with politicians. This notion that more politics will fix thing isn't born out by Reddit, X, the US Congress, Brexit, etc. It's too easy to divide and manipulate people.
