Though I would kick the can back, to say --- > though yes, nuance is important, the concept of "open-mindedness" should not cause us to lose our way so far as to say there aren't Core Values that America should stand for.
e.g. the U.S. Army has committed to Loyalty, Respect, Integrity, Selfless Service, Duty, Honor, and Courage as "good" and their opposites as "bad." It is very specific as to what it means by these, and (in the main) creates Soldiers who exemplify these these, as opposed to kids nowadays who often exemplify Disdain, Grievance, Expediency and so forth.
I'd get an argument from a lot of twenty-somethings I know that such attributes are "good" even in the abstract. 50 years ago, we wouldn't be debating whether it was a good thing to tell the Truth, whether the Founding Fathers (much less Jesus or Moses or the Dalai Lama) were basically positive role models, and so forth.
The 2016 A.D. culture war in the U.S. is fighting on some awfully thin ice, in my view.
Good stuff amigo.
