This is a fair point and valid data point for how people view it.
Only thing I'd say is, to me the reasoning seems related to a sentiment that's I've seen in a lot of places, that after all the nastiness that's built up through the course of the (very long as usual) US election cycle, it's time for everyone to cool off a bit. So my instinct isn't to tie it that much to anything about HN in particular. Now of course, the same point applies outside of HN - it gets a lot harder to treat Trump as a topic you can just stop talking about when you're more likely to be directly and immediately impacted. And then there's the idea that we shouldn't normalize him by treating him like a normal candidate where, after the election, even if your ideas lost, at least you know there's a modicum of competence and civic-mindedness at the helm… Still, despite all that, despite the fact that I attended a protest myself (just one so far), for me some of the sentiment of wanting to cool off still rings valid. Maybe it shouldn't - but then it's not like we can do anything to change the election result; we're all in this for the long haul…
There's also the fact that "politics" as described by dang covers a lot more than US electoral politics. But the reason for wanting to avoid it is still the influence of US electoral politics on those conversations.
I definitely understand electoral politics fatigue. We're all having that. But 'dang explicitly said the intended scope of the ban/"detox" is wider than that, over in this comment: https://news.ycombinator.com/item?id=13108614
"The main concern here is pure politics: the conflicts around party, ideology, nation, race, gender, class, and religion that get people hot and turn into flamewars on the internet."
So apparently literally anything about race, gender, or class (which are really important issues both in terms of the tech industry and in terms of who technology is for) are considered off-limits for the week. (And at least one relevant story - about big tech companies releasing diversity reports - has already been killed under the policy.) That is one reason I am taking this as such a clear signal of the values of the mods, rather than simply a reaction to election stuff. I could be wrong, of course, but i wanted to try to let you see what i - and many others, i think? - are seeing that concerns us.
