Typically when I find my statements are downvoted it is because I had a quip that could reasonably be construed as negative, combative, etc. I tend to edit and remove those bits.
When I find things to be "reflexively" (probably the wrong word) downvoted, it is in regards to simple questions. Simple example, there was an article regarding Manning's confinement yesterday. One top-level comment asked "Why is this not cruel" to which I asked the opposite, "How is it cruel?" - simple as can be. I watched that one go down to fairly negative, then bounce back up, settling on a score of 0. I don't care about the score itself so much as what that delta represents.
Perhaps I'm just too narrow minded, but I fail to come up with a reason to downvote a simple question asking for perspective that doesn't involve me reading some kind of intent. One of the core tenets of this site is to assume good faith, assume the most charitable viewpoint. When I say that I believe HN culture is dying, it is this that I am talking about. There seems to be less and less good faith discussion as time goes on.
As always, I'd love for an alternative perspective that I'm (probably) missing here.
