What you are pointing out here is fundamentally true and verifiable. I think I find myself, along with many other americans, in a bizarre position where we see comments like this which we know are accurate get barraged by downvotes or whatever system in Internet commentary exists to decrease the visibility of the comment, and I find this troubling. This mostly happens, from what I've seen, if there is any suggestion within the comment that the right is in some way defensible. I think many internet forums have tried to use downvotes as a signal for validity, but so frequently that signal is obviously misapplied, making it almost entirely meaningless. In fact, it is has become a signal for the direction of the political leanings of the majority, rather than anything having to do with the usefulness or appropriateness of any given comment.
This is probably a bad thing.
