One side being the majority doesn't make it an echo chamber though, every forum will have one side that is more prevalent than the rest but as long as the other sides are still allowed to post and get upvoted to the top when they make good points it isn't an echo chamber. I see both conservative and progressive points get upvoted to the top in different threads, that is strong evidence that this isn't an echo chamber. On r/politics I never see right wing opinions get upvoted to the top, and on r/conservative I never see progressive opinions get upvoted to the top, that suggests those two are echo chambers unlike here.
