In the longer run, I think it is good to have some politics on the site. Technology doesn't exist in a vacuum and has a huge amount of intersection with politics. In the past, it has been possible to have rational and nuanced conversations about political issues on HN.
In the recent election cycle, that's been destroyed. It seems to have emboldened people to derail threads with political mud-slinging and the crazies have come out of the woodwork.
To put it simply, I never thought HN would be the place where I was first told to leave the country or get killed. The fact that it was (and not Reddit) honestly depresses me, and I hope that a detox period will force the worst politics out of the forum.

That being said, I see a lot of people pointing to "incivility" as a problem in political threads. That is incredibly wrong. The problem in political threads is twofold: (a) people civilly arguing without actually acknowledging each other's points at all, (b) hateful rhetoric which destroys a sense of community.
If you want evidence of how civility is not the problem, take a look at this thread where a long-time commenter (with >12k karma) civilly, calmly proposed the mass deportation and/or murder of Jews: https://news.ycombinator.com/item?id=13056816
