Head over to lobste.rs, not much activity but it fits your description.
HN's political discourse has been quite unpleasant since last couple of years. Used to be quite a gamut of perspectives, now it is completely lopsided.
Worth noting you have to be invited to join Lobste.rs (by a current member). I'm not one, but the discussions there are often interesting - IME about half the stories I've seen here first and on those stories in general the Lobsters threads are a bit more technical and a bit more focused.
I quite like the 'what are you doing this weekend threads' it feels very small-community-like. [But that might just be that I've often felt a lack of tech community - as an example, I've used Linux for >20 years and don't have anyone in my life I could have a conversation about it with like you might chat to a neighbour/friend about pruning a tree or fixing your car.]
