Hacker News has never been an anything-goes site. Tight moderation, considerate rules, and low tolerance for bullshit have made this a great site to talk about interesting technical topics and ideas. Remember that we all abide by the rules of the site, and that this isn't a magic free speech zone. If you want to talk political topics, the Internet has more than enough outlets.
Political discourse is antithetical to rational, intelligent discussion. This is not an opinion; look only to sites that allow political discourse (Slashdot?), or even our own comments to see how quickly rational discussion can devolve into flaming. One of the major selling points when I introduce HN to other people is the _absence_ of political topics or discussion: leaving the politics out just produces better technical content.
Also, please consider the idea that politics are regional and differ between countries. In Canada, where I'm from, many of the US political topics would never come up; many European countries might feel even more strongly. As a Canadian, I find American political musings and arguments even less relevant and noisy. By contrast, technological topics are always interesting to me - I can appreciate these, and I love that there's this corner of the Internet where I can participate in a reasoned, interesting technical community. Please don't ruin it with politics, especially the polarizing American variant.
I appreciate that the site is willing to take this step, and I sincerely hope it can keep this site useful, interesting and level-headed for the future.
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
I think you're right that both of those are problems, but they're not the only problem. Incivility is also a problem in political discussions here lately. Another problem lately is that discussions to which a political discussion is only tangentially relevant get derailed by political discussions that exhibit these problems.

I disagree with this for two reasons. Firstly, if people could civilly propose the mass deportation and/or murder of Jews, then that wouldn't show that people proposing either that or innocuous things incivilly is not a problem (only that incivility is not the only problem). But here specifically, I don't think that commenter spoke civilly, any more than "No offense, but <some insulting or offensive thing>" is polite (indeed, less so, as the commenter made even less pretense). The civility of discourse isn't independent of the content of that discourse.
