I think more people should see this.
I can't agree more with your comment about wishing people would reply with reasoning rather than simply downvoting.
When I jump into a heated conversation or comment on an emotional topic, I am fully aware that I'm asking for downvotes without responses. But that has served as a negative reinforcement for making said comments, which leads to me engaging in those conversations much less often.
My point is, I'm not sure this is a bug. I'm pretty sure its a feature.
