The single most facile, reductionist and dangerous example I can think of which conflates church and state is this phrase:
"God-given right to own guns."
The instant people embraced this sentiment as not just normal but immutable, there ceased to be any limit to what they can believe or justify.
@ErFlynnArt Yes, exactly, it speaks directly to the value of life.
In this view, the value of life is weighted toward the people who have the power, and the presumed will, to end it.
It's both the root and the fruit of the might-makes-right doctrine, which is itself infused with paranoia.
Ensuring all paranoid people have access to death machines is pretty obviously not the best public policy. But questioning this as a (God-given) right feeds their paranoia, which is layered and complicated.
