I agree, but i still find problems with it. Such as, as westerns we want to seek a Utopian society, but under a different group they wish something completely different. It wouldn't even have to be opposite, just something else, like they are an isolationist hunter gather band and wish nothing of modern troubles. Or it could be a group that think God put them on this planet and their survival comes before anyone else's, so to ensure that they want everything and want to kill everyone. My point is who's to say who's right or wrong? If westerns decide that a Utopian society is best because it will provide the most amount of freedom to the most amount of people, and there is dissent, what do you do? How do you enforce something like that?
And of course, What would the moral codes be?
