It’s not that the quality of politics posts here are very high (you get plenty of “engineers outside their domain” type stuff). Just, it is hard to find sites with

* Active political discussion communities

* That haven’t swung dramatically to some extreme and eventually worn down the local “opposition” party

I’ve got boards I go to for politics but the ratio is so lopsided, and the one or two remaining posters that disagree with the consensus seem to be more or less sticking around out of contrarianism (which unfortunately decreases the quality of their posts).

I think if HN let too many political threads stick around, that would destroy the whatever quality the discussion has.
