That's certainly a big problem, but HN can't be a site for intellectual curiosity and at the same time exclude every story with political or ideological overlap. People sometimes imagine that that would be better, but only in the context of a specific story or thread they don't like. If you try to imagine it as a general policy it breaks down altogether. Nor would this community accept such severe restrictions on the range of topics. I don't think we have any choice but to patiently work together at having more thoughtful conversation.
I've written extensively about this: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so.... Some good threads to start with might be https://news.ycombinator.com/item?id=21607844 and https://news.ycombinator.com/item?id=22902490.
If anyone has a question that hasn't been answered there, I'd like to know what it is, and if you know a better way for HN to relate to political topics while fulfilling its mandate of curiosity, I'd really like to know what it is. Just please familiarize yourself with the past material first, because if it's something simple like "just ban politics" or "just allow everything", I've answered many times already why it won't work.
