You are aware that religions are a form of superstition? It would be more correct to start substituting 'fundamentalism' for 'christianity'. Though I agree that superstition of any kind should stay out of decision making.

Trying to argue with the bible won't work. The devil can also quote from the bible, according to their mythology. They won't believe you unless you're a devout christian. You have to make sure others aren't infected by this insidious memeplex instead.
