ELI5:If downvote *isn't* a disagree button, what is it exactly?

Votes are for prominence relative to other posts. Upvote something that should be seen, downvote something that shouldn't or doesn't deserve to be seen for whatever reason.

If you want to label it, I'd call it a "hide" button. As you know, posts under a certain score aren't shown, and posts with low scores aren't featured on the more heavily trafficked front pages.

People will often downvote something they disagree with (even if it's accurate and relevant). If you ask me, they should reply in disagreement, and upvote so others could see what they mean.
