The decline in the influence of religion has been due, in the main, not to religion itself, but to the very shallowness of many practitioners. People who are indoctrinated and mistake implanted obsession for faith, are themselves destroyers of the very thing which they imagine themselves called upon to try to protect.In fact, of course, they have no such call: and their capacity to protect something which is other than their imaginings makes for a comical situation.
