For example, engaging epicureanideal's post with arguments showing his opinion to be wrong, instead of just hiding it with hundreds of downvotes. That post and its replies was like 90% of the discussion when I first checked, and now it's one light gray row at the bottom. As is, there isn't much of a discussing left in here.
Please don't comment about the voting on comments. It never does any good, and it makes boring reading.
Please don't use Hacker News for political or ideological battle. That destroys the curiosity this site exists for.

The "hundreds of downvotes" and how the UI reflects the downvotes are two facts of life. Indeed your initiative to change these facts is not interesting to me.
I was trying to comment about the lack of different opinions in the discussion. Because it's hardly a discussion if everyone agrees and/or if the people who don't agree are invisible.
