I sometimes have to wonder about the mind set that makes people believe such quackery. Same mind set that believed in witchery, black magic, hobgoblins, etc. in the old days. People used to actually believe that if a black cat crosses the path in front of you, it would bring you bad luck. So would breaking a mirror, walking under a ladder perched against a building, stepping on a crack, and a multitude of other nonsense.
Applied to the modern world, this would almost be funny if it didn't bring about avoidable deaths and lifelong suffering, sometimes to the ignorant people's own children. It is obviously not funny at all, it's a tragic example of denying reality (scientific proof) in favor of superstitious nonsense.
Yes, big pharma makes a lot of money. But what about the quacks who promote their twisted take on reality, via their books, speaking engagements, etc.? To a naive audience, finding a Biblical passage (and there's one for absolutely every idea, good, bad, or totally ridiculous), coining a new impressive-sounding term, etc. is enough to convince them. Of course, the drug companies imply plenty of nonsense in their TV ads also; that's what common sense is for. Should something be believed just because it's "different?"
When the nonsense reaches the upper echelons of national health policy (can't go any further without venturing into politics) it becomes frightening and sad, especially when it prevents other people from being healthy, or even alive.
