The conversation in the blog post presumes a certain shared understanding of the facts. When you push a conversation out of a context of shared assumptions or understandings, then you are going to have to expect push back. I don't think that says anything bad about HN here. All you are getting is feedback on what a large segment of people think. In some alternative world they may have agreed with those background beliefs, and then the pushback would not have occurred (or it might have pointed in another direction). If the article had approached its central question--whether to tell people or not--by first saying something like "suppose that we knew the civilization is going to collapse in the next ten years, the question arises: should we tell people?", it could have avoided more of the pushback it received.
