This is exactly why fact based discussions not only don't work, but don't happen on hacker news. Because you can just say something different. And that is how it always is. Someone posts a citation and someone else goes out of their way to debunk it. Then they just say something else. Next time no one bothers. Because the point isn't to have a fact based discussion, but to not be questioned on an already existing view. And that is what the article correctly caught on to.
