You comment and argue like what you are doing right now. If we have way too many junk posts flooding /new then there's not enough time to comment on them all. When you click on a post, what else do you notice beside the upvotes? The number of comments. If you see a post with a massive comment thread you would be more encouraged to participate. Whereas if you see like 200 new posts with 5 comments or less and a couple of upvotes spread out, you don't really feel the urge to participate in them. Even if one post has what you want to talk about, no one's commenting on them so you won't really be able to get a discussion going. And then that one post you're interested in will just get quickly flooded up by 20 other posts being posted in /new.
