The downvote to my comment is case-in-point. Somebody disagreed with what I was saying and downvoted me. I broke no HN policies and my comment was on topic. If they were required to enter a reason as to why they downvoted me, and their name made public, it's highly unlikely they would have downvoted me just because they disagreed.
