I see dead posts. I also habitually look to the bottom of the page, where the controversial opinions are. New submissions are usually more diverse than the home page.
There's very little sport in defending an establishment or consensus position. As they say, if everyone is thinking the same thing, then someone isn't thinking. There's almost nothing to discuss if we all agree.
There's a fair amount of downvoted and flagged content I agree with. It doesn't stop me from reading it. Like Twitter's "fact checks", it draws my attention. There are some topics where even if I agree I can see how those who disagree are incapable of discussing it without devolving into an all out flame war.
The real horror show are HN's shadowbanned accounts. 99% of those are awful.
