I find that trying to debate anything in the post-truth climate, even on this board, is pretty much an exercise in futility. Both sides of the argument will produce oodles of links, proving just how right they are, while at the same time being dismissive of the sources from the other side. It's amazing how there is never consensus on any topic, but I guess it's not surprising, given that the internet provides tons of "facts" from "experts" for anyone seeking validation of his viewpoint. It's so easy to settle on an opinion, then go out and find articles, documentation, editorials, statistics, facts, opinions, and (lol) tweets that will align. Heck, some posters even use their own prior posts ("I posted about this months ago, so...") as some sort of voice a authority.
It reminds me of the story of the 5 blind guys and the elephant.
