It is possible to talk about these topics from an academic perspective and it feels like banning it for a week is equivalent to putting your head in the sand and ignoring it because its too hard to have a conversation about it. This is exactly the behavior I was motivated to try and change in myself (stick to tech only, ignore other issues).
Yes, its very difficult to talk about some politics in thoughtful ways but I would hope a community like HN has the people needed to try and address some of the issues coming up. Be it technical (detecting fake news, biases, etc) or intellectual commentary.
