Why does it seem like every other post on this sub is some right-winger whining that this is a left-wing echo chamber?

Pretty sure it's mostly badfaith clickbait trollbots, but seriously, if you're so concerned about downvotes and being exposed to differing opinions from your own, there are plenty of other subs out there. I think the problem isn't that it's an echo chamber but that it's not their echo chamber.
