There are a ton of other sites where you can follow and debate politics all you want.
I'm starting to stick my nose into local politics here in Bend, Oregon, but there's no reason I need to talk about it on HN. I'm ok with compartmentalizing things: HN for tech/startups/'interesting things', and other sites for other things. I love bike racing, too, and feel that it's the best sport in the world, but I see no need to introduce bike racing articles here.
But where do you draw the line of what is 'politics' and what is 'cool nerdy tech stuff'?
Is a breakdown of 538's method of poll aggregation too politically charged, even if there's a perfectly good overlap of math and statistics?
If Trump makes an out-of-left-field statement about repatriating corporate money, are we prohibited from talking about how it will affect Apple?
A blanket ban of 'political threads and topics' seem harsh, even if just for a week. I personally haven't found the political content on this site to be out of bounds, considering the monumental political upheavals we've been witnessing over the past year.
Politics is about how resources are allocated in society and can often be a very effective solution to problems.
It's often pretty obvious from the ensuing conversation what kind of post it is: are people discussing the politics, or the technical thing that's kind of related?
If you start a business, politics impact you. If you are an employee, politics impact you. If you invest in businesses, politics impact you in a huge way.
Uber and AirBnB are no longer just startups, they are very politically active corporations. But they both started, if not from here, then from other communities just like this one.
That's another reason why it should be banned, because it will crowd out other topics by dint of being more important to more people - which is also a feedback loop, as more people get drawn in for the politics.
See, that right there is a political statement in and of itself.
An extreme case would be a Dr Evil figure who will not examine his own heart and needs the world to burn just so he can pretend to himself that he's a good person. So he makes the world burn. At every stage convinced of his own righteousness.
This explains why 'war is the continuation of politics by other means'. What passes for peace is trench warfare where the only progress is sideways. Improving the machinery may be desirable but in practice politics is dominated by preventing inevitable perturbations from escalating into open hatred and violence.
(More parochially one can tell when politics is influencing the discussion because there is always blaming going on.)
