Sorry, that is way too optimistic. It will never be a universal standard and I think that you understand that. Think of applying the same rule in Iran? Enough of this banter... You and I both know that anytime people make the rules, it can never be sustained. Feel free to apply your logic to other discussions...
The problem with Iran is precisely the fact that its people are ossified with a barbarian theology that prevents them from applying the Golden Rule both amongst themselves, and with others.
The fault in their ideology is that it is stuck on Old Testament morality, where archaic, tyrannical rules are allowed to dominate over any application of the Golden Rule. Hence such barbaric punishments as stoning, amputation and decapitation. It took Jesus to change that in the Middle East, with a basic philosophy which was the Golden Rule.
That said, I agree this has been a long, winding discussion amounting to not much.
Good day!
