I read about politics all day long in many different places. My belief that HN should be relatively free of such stories is not because I believe I can detach myself from politics, but because I believe topic based forums are more valuable and useful than “anything goes” forums.
Not only does politics and general stories crowd out everything else over time on other sites, there are HN submitters who seem to be trying to accelerate this.
During the war, when HN was getting Israel-Palestine stories constantly, I started looking at the submission history of some of the submitters, and some of them were just pushing these types of stories every day for months and months.
So yes, I think allowing politics will eventually mean being dominated by politics and general interest.
If HN is going to allow accusations to be slung against groups of people it has to allow others to respond, and that sets off endless debate amongst people who will not be changing their minds on the matter but will repeat the same argument on the next post.
