Those sort of discussions are probably most effective when had in "meatspace" (I dislike that term, but I dislike the term "real world" even more). No 'throwaways', fewer 'throw away opinions', no voting systems or flagging, greater communication bandwidth (access to body language and tone reduces misunderstandings), etc.

Trying to get HN to productively discuss topics like this is like trying to get 4chan to "count to 10". The site just really isn't set up to facilitate it.
