Jerky can be and is made from all kinds of meat - indeed, the word comes from the Andean language family Quechua (the dominant languages of the Inkan empire), Ch'arki, where it is made from llamas and alpacas. Why would long-pork jerky need refrigeration?
And before your brain rejects that as too insane to be real, ask yourself this: Why would the richest, most powerful people on Earth waste their time and money on rituals that don’t work? These are not stupid people. These are the most strategically intelligent humans alive. They built fortunes larger than most nations’ GDP. They control governments and intelligence agencies. They don’t do things for fun. They don’t waste resources on theater.
No. This is the truth you are trying to escape: That the world is indeed run by idiots, powerful not by any true talent but low cunning in navigating and using perverse systems of privilege, who do indeed do sick and depraved things because they are sick and depraved and have the power and corrupt protection to live out every sick and depraved fantasy of theirs with minimal risk of meaningful consequences.
