I view downvotes as an incomplete feature. If you disagree with some content -- because it is misinformation, or useless, or maybe you just disagree with the argument -- you should be able to explain what's wrong with it. I would much rather have a system where a downvote required a reason, so instead of a downvote it would be more like a comment which can also -1 / 0 / +1 the karma of the parent.
