>The first is that human beings are, under ordinary circumstances, about as reasonable and decent as they are allowed to be, and can organize themselves and their communities without needing to be told how.

That's a crock of shit, look at how brutal early civilizations were compared to today. You have an argument over long terms (100+ year spans), but not in the near term.

If you want the assumption to apply to the near term, you have to accept that people behave in part based on the laws and society which they grew up with, which then makes you look weird for being against that system. That's what gives rise to the common decency.
