The submissions all have tons of comments (including by many of HN most prolific and high rated users). Sure the conversation is messy, but that is often the nature of important conversations. We have to talk about things which make us uncomfortable. We have to talk about events that involve gay right, human rights, etc. when they involve new technology companies. If we don't, we are not being responsible humans.
HN has implicit standards for discussions. There are many many places on the internet where this story can be discussed. Indeed, there are places which embrace opinions about the Bush Administrations, the Obama Administration, what is the proper nature of American patriotism, and what role the US and it's corporations should and do play in international affairs.
But for better or worse, HN is not really among them.
