RoadRunner, thank you for your thoughtful and nuanced approach.
Observation does seem to support your statement "most people behave as if there is a moral realism. That morals are objective, and actually honorable or wrong, regardless of the subject, time, or culture." Certainly most of us tend to behave as if morality could be objective, regardless of whether or not it actually is (or could be) objective.
On another matter, I see an additional problem with Little Henry's insistence that morality must be grounded in a supreme being of some sort. What happens when the belief system or the attributes of a god change, as they so often do? The nature of the being that one believes in will largely determine what is considered good or bad in that system.
