Plenty of stories with political overlap [1] still get discussed on HN. Your list seems cherry-picked to me - presumably because those are the topics you dislike, and mostly people overemphasize, and are more likely to notice, the data points they dislike [2].
I'm not sure where you got the idea that HN doesn't have rules, but it does, and they certainly exclude abusing other members [3], doxxing [4], etc.
