This is why twitter and facebook don't have dislike buttons. By removing a quick and easy way of voicing dissent to a point, people take to the comments to verbally punish others. For a site that is dependent on user engagement, anger/outrage/frustration/negativity in general is a gold mine. I remember when reddit tried removing the down vote button the comments got NASTY. They back-peddled very quickly from that decision.
