Picture, say, China or Iran controlling one sixth of US hospitals, with power to decide which patients and medical procedures they will or will not handle. Picture them spending millions—maybe hundreds of millions—on a decades-long campaign to win taxpayer funding for brainwashing American children into believing how wonderful the value systems of China or Iran are. Then picture that same country demanding an exemption from the foreign disclosure laws, simply because it promotes unprovable beliefs about the supernatural.
Is this picture OK? And if not, what makes the Vatican different?
