I always felt that these things tend to get blurred together especially when tensions flare. The ideal situation for a downvote may be something that doesn't add much to the discussion, whatever that means, be it somewhat off-topic, repetition of existing information, or groundless speculation. The vote helps move that conversation down and ideally allow better more 'additive' ones to float up. But on pure disagreement, it seems like a missed opportunity to discuss. This is unrealistic, but I'd love a middle option between downvote and super-downvote (i.e. flag), where you are required to reply. The extra effort would prevent knee-jerk reactions that silence acceptable comments, but maybe would foster some constructive disagreement now that your username needs to stand behind the downvote.
