I don't think it should be that difficult. There are plenty of people in P&S who post absolute nonsense, but at least manage to mostly stay on topic and can make a coherent post, even if the content of that post is moronic. And then there are people like BADecker and Tash who just post low quality and off topic trash which contributes absolutely nothing to any thread.
We delete off topic posts and posts which add nothing in other boards. Why not P&S?
I do agree somewhat, there's definitely a few cases of pretty straight forward off topic replies, or just genuinely low quality posts. Although, I do think you need someone in the P&S section that probably doesn't care all too much about politics, otherwise personal beliefs, and views can get in the way.
FH was a left-wing Bernie bro, and IIRC was a supporter of communism. That is far from moderate, and he did care about politics.
IMO, it is more important for the P&S mod to be able to moderate in a way that is viewpoint neutral, and will not allow his views on topics of discussion interfear with his decision making.
