I used to spend a lot of time on metafilter, but I've soured on it's politics. Like I knew I was pretty far to the left of a lot of folks on the site and I'm ok hanging out with people I disagree with. But the self-righteous nastiness and lack of self-awareness is really offputting. (eg https://www.metafilter.com/167767/Covering-America-for-the-world-including-Americans#7073563) If you you plot politics on a graph,that user is closer to the Rs than to me.

The kind of mefites that drive me up the wall are the ones who comment in one thread about how Republicans are all fascists trying to kill trans people and you should totally punch nazis, but when you point out elsewhere that the policies they support are really bad for say Syrians or disabled or poor people they claim they're "just being pragmatic."
