My position is that morality exists as a fact in its own right (Human Vitae's smug voluntarily moral blindness and studied obtuseness notwithstanding) and serves as the foundation of all just laws. Many acts and behaviors that are immoral are best discouraged by informal personal censure without the intervention of government. But when this informal personal censure breaks down and dissolves, when each man is the arbiter of his own morality without regard to the external costs he thereby imposes on his neighbor, destructive anarchy can be avoided or forestalled only by the imposition of external controls on behavior. A man who will not control his immoral appetites internally runs the risk that a tyrant will seek to control them externally.
I would much rather live in a libertarian society comprising moral and just men and few laws. It is the moral relativists who have made that society impossible.
Thought we were on the same side, Kev. Anyway, I suggest you pick up any dictionary of philosophy and look up the fact-value perplex. You'll learn something. Don't worry, it won't hurt you.
