making participation in the community feel unproductive or useless
STOP SCREAMING IN MY HOME

This is the thing I find more important than the rudeness — you end up without a community at all, not just one that seems predominantly unpleasant. I don’t think YouTube will ever solve this either because the comments are a perfect place to scroll-comment-leave, no matter how hard a creator tries. Honestly I feel to have real discussion, you have to make the viewer put in more effort than just scrolling down, and a system more understanding than upvote/downvote or number-of-replies.
