HN is a social echo chamber [http://mjg59.dreamwidth.org/28232.html]. Given it's libertarian leaning, it would be a big surprise, if it would try to objectively assess a topic that is under heavy propaganda from all sides.
You're right on the important thing, though. It's too much to expect HN to "objectively assess a topic that is under heavy propaganda from all sides". Objective assessment requires time, calm, reconsideration, and a high ratio of information per conclusion—plus a discourse in which people respond first to what is true in others' comments rather than to what is false in them. That bar is too high for an internet forum, or at least this one.
