In all seriousness though, there's really no point in having the ability to downvote comments. Good/popular posts already get moved to the top because of people giving a thumbs up so that system is already there. Thumbs down could have a place if used to filter out comments that are straight-out trolling but as is people use it to get rid of/hide opinions they simply don't agree with, and opinions getting hidden because they're unpopular is, as Pokoko said, bloody fucking stupid.
