Proposition: the US is founded on moral relativism

A test for absolutism:

“Doing A is bad.”
“Says who?”

In this case, the authority to appeal to is the dictator… there are no other sources of moral authority.

Excepting logic, I do not see how those are more objective in an absolutist sense. The appeal to multiple decision-makers for majority rule within a specific culture is as about relativist as one can get.
