Meta note: I saw that this post was being pretty heavily downvoted and upvoted it to keep it from falling out of the discussion. I disagree with the assumptions in the post, but they are handily refuted by replies. I'd rather have a robust discussion with every reasonable side well represented than a boring echo chamber.

I urge other folks here to not merely blindly downvote posts they disagree with, reserve downvoting for posts that don't deserve to be seen at all because they don't contribute to the discussion.
