Of course it's BS, it's based on religion. The more interesting question is whether indoctrinating young kids into their parents'/society's religion is actually harmful, or if it's just a harmless tradition (e.g., Santa or the Easter Bunny). This is an extreme case, but what about the "average" parents who teach their religion to their kids before the children are old enough to make their own decisions; is that also harmful, or is just harmless fantasy?
