Politics are also never discussed with any level of depth. At best, it each side throwing in their opening arguments and nothing more. More often you don't even get that and instead have attacking people directly, stereotyping, straw manning, and all sorts of logical fallacies. Discussion in such a situation does not happens, so either it is an ongoing war or some side wins and pushes out the rest. None of these outcomes would seem beneficial for here, and while I do think there would be some slightly longer form discussions here compared to most places, I don't think it would be enough to avoid the eventual decay.
