I see nothing ‘controversial’ about a doctor refusing to perform treatments the state permits but that violate his own principles. Do we want doctor’s being forced to do lobotomies on ‘enemies’ of the state? participate in final solutions?
You touched on our Unalienable Rights, the Natural Law philosophy of our Founders. No one need tell you that killing innocent babies, performing lobotomies on political enemies, or final solutions are wrong. No human law can make them right because they violate Natural Law and as such are not morally enforceable.
We are a civilization in decline in large part because the Christian basis of our Declaration and Constitution have been purged from schools and our traditions.
