I really worry for the people in the US, but I'm hopeful it's hegemony is ending.
The issue, of course, is that literally anything can be "political", and moreover by trying to actively avoid political discussions you sort of tacitly endorse the status quo.
It's a tough line to draw, and I'd be lying if I said where I knew where to draw it; HN is a fun forum specifically because the moderation is generally very good. They're not perfect but they do try and shut things down before they devolve into flame wars and personal insults. If there weren't aggressive modding, HN would devolve into 4chan or 8chan, and it wouldn't be appealing to me after the age of ~17.
