When I said a lawyer might argue the pastor really believed his "milk" was holy and you'd have to get into the pastor's head to disprove it, I meant the _lawyer_ could argue that we'd have to do that. Evidently the whole story is a hoax, but if it ever happened, I would not be one to try to excuse or rationalize it, even if the man was so deluded he believed his own lies.
I do sometimes wonder to what extent various cult or movement leaders believe their own claims. Are most self-deluded, outright charlatans, or a some mixture? To me, it's not always clear, even when their teachings are pretty outrageous or whacky. However, when it comes to some cult leader coercing followers to sleep with him for some supposedly religious reason, I have little doubt that he knows full well that neither his actions nor his "milk" are the least bit "holy."
