It's a very frustrating thing about this site, because, ironically, most people here think of themselves as nearly perfectly rational and open to new ideas, but in fact the opposite is almost always the case. If I think of myself as perfectly rational, that ironically gives me a way to think that anyone who disagrees with me must be trolling or must be saying something obviously wrong, even if I don't take the time to work out what that might be.
I admittedly added that just to complain, expecting it to trigger another wave of downvotes - because frankly, I don't care about getting downvoted. What I care about is how often this site turns into an ideological echo chamber for one of two popular worldviews, and on some level I wanted to try to call attention to that.
That's not true, I downvoted the past because it complained at being downvoted.
On an individual level the thing to do would be to upvote downvoted posts if they make some sense, they don't have to be great to be upvoted.
