This is exactly one of the problems. People downvote because it is how they feel not because there is any logic to it. Unless the negative points reaches threshold, it is suspect. Downvoting should also consist of a comment as to why. When a professor marks your paper wrong, does he not place things on it like "W.C." and so on? How are people supposed to learn from their mistakes if they think what they wrote was reasonable yet some HN user comes along, misunderstands what was written, and just votes it down?
I downvoted you because you quickly played the "personal attack" card in the same breath as you laid all the blame for what you perceive as a slide in HN quality at the feet of those who upvote different stories than you would -- which amounts to a personal attack. The obvious loop in your argument makes your comment uninteresting.
If that doesn't make sense to you, just give it a few more minutes and the submission will probably be flagged dead.
