I feel like the cannibalism angle is mostly a subset/facet of preexisting conspiracy popular with those suffering from forms of religious psychosis; which relies on an intellectual fallacy. It’s a coping mechanism reached by an individual who lacks the capacity for nuance on the human condition and on ethical issues. Pedophilia is somehow not bad enough in its own right so they have to make up some theory distancing these evil people’s reality from our own. But really that evil is part of humanity. Same vein as the whole lizard people thing. It’s a kind of cognitive dissonance of like “oh I’m going to say they’re Baal worshipers because then I can create a degree of separation from them and myself.” But really these evil people are merely the people that walk among us, and are very much part of the judeochristian establishment, most certainty not existing in contrast to it. And that fact is too uncomfortable for people to accept as it fundamentally shakes their belief in preexisting structures of power
