I disagree. Upvoting is like a High 5, downvoting, especially on Reddit, is used to bury something people don't agree with. Downvotes, IMO, should require some sort of intellectual effort as to why you are actively burying a comment or post and thus require a reply.

Dragon, you commented and downvoted on something that you are doing right now which is commenting on a comment system. No? At least you had the decency to reply, which most Redditors don't. Which makes Reddit Toxic.
