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 see this great move as a way of the community lifting its head out of a sandy quagmire to glance at the shining beacon, the vision on the hill, the where we want to be, unsullied by political nausea. Sure, in a week we can get back into the grim reality, the tech-noir crapsack future, but perhaps for one week we can focus on a positive future and its soaring aspirations. Go Dang!
I don't think politics have overtaken the site or even become a significant part of it, so I wonder why politics-averse individuals cant just avoid political threads?
It is indeed possible to avoid clicking on a specific kind of topic. From what I understand, the issue here is more that it just isn't a fit for the purpose of this community/website.
