Why do jabbed people sometimes get mad when you tell them?

Not always but it’s a phenomenon that happens a lot that when you try to tell Jabbed people That there’s something wrong or they’ve been marked or it’s dangerous to them, they get real defensive and belligerent about it like they’re invested in there gonna double down and go down with the ship rather than admit there’s a problem. Like at that point they don’t want to think about it anymore even if it is deadly. There is a psychological reason and Dr Zelenko explains it.
