The way this sounds is that you are more concerned about politics as in people who take party positions and may feel excluded as a group when the majority of the community takes a different position. This is a slightly different issue i.e. party politics, and I think it is fine/a good thing, but it is also important to distinguish the two. This should essentially be under the same umbrella as personal attacks, as they are essentially the same thing.
I'd rather see HN go politics-free forever. Political discussions do not enjoy the same level of objectivity that technical and business discussions do. Frankly, it may be impossible to expect objectivity within political discussion because our political feelings are so deeply-held and tied to our individual upbringings, culture, and locale.
Unless HN can figure out how to give fair treatment to minority opinions, it's best to exclude these discussions entirely.
I have to admit, it really irked me at first when I came here. How can all these people that like the same things as me, have ideas that are so ... "wrong?!" (just kidding, honest :) ) But then I learned to listen and realize that these opinions will be here whether I engage them or not.
Of course, I see subthreads that aren't very "objective in the way I want them to be". But I don't share your experience with downvotes. I try to refrain from trying to convince the person I'm directly replying to if their view is directly opposed to mine, that never works any way. I just state my own personal position and how it reflects. Sure I get the occasional downvote but that's almost always when I've let myself be confrontational about it. Also, there's a big difference between providing a link to some facts that a person might not know, and a very opinionated link (that may also have facts and numbers) that is arguing your point.
So yeah, while I support the experiment (it'll be interesting to see), I really hope they don't extend this to forever, but just occasionally after particularly turbulent US elections.
Finally:
> fair treatment to minority opinions
Come on what does that even mean? I don't know what your opinions are. You don't know what mine are (you can read my comment history but good luck). I have no idea what "fair treatment to minority opinions" should even mean. My opinions are minority opinions too (I'll change them if you don't believe me), but I know this; People that complain their opinions aren't getting fair treatment are very rarely worth listening to, regardless of position. I prefer a better signal-to-butthurt ratio.
I feel this opinion falls into that category
Unless you mean something different, maybe the line could have used some qualifiers. So it's not the opinions themselves that aren't worth listening to, to be clear. It's just that given two people of the same position, the one that's not complaining their opinions aren't getting fair treatment is usually one that can argue their position a lot more clearly and therefore is just generally more worth listening to. Although that's the less-accurate positive version of that preference of mine. In my personal experience, the negative version is almost always on point.

You didn't say "more" or "less" worth listening to, you said "not"
