I disagree with the decrease in discussion quality. Votes inherently create echo chambers. We have low effort conversations where we all downvote someone whose opinion is different and it makes them feel whatever kind of way, and they act accordingly. Whether it be leave, lash out, or discuss. If it wasn't built in and someone wouldn't already know I would say it is a bad idea, but since it will exist, making it so people learn to be civil is probably best.
