In my experience, battling it out us part of the problem. HN already allows people with divergent views to discuss them. Discussion of that sort is enriching, with no winner and no loser. Sometimes views are changed, but it helps to assume the world is not black or white, not even shades of grey, but is a rich technicolor universe and sometimes we run across people who know things we do not who thereby have the capacity to broaden our views.

And battle is not how you get there.
