My position is that downvotes should not exist. There are three ways to view posts and comments: A. you agree with it, and appreciate it, so you upvote it to give it more visibility because that is how this whole system works - popular stuff should rise to the top, and an upvote is a measure of popularity.

But this is probably a crazy idea, so feel free to downvote me ;)
