Have you ever tried to real life red pill someone who is thoroughly brainwashed? They either shut down or start lashing out in ways that don't fit their personality. I've learned through experience that it's a "Fight or Flight" response–their brain literally sees your information as a threat and responds as if the person were in danger. They don't even have conscious control over their reaction.
Being presented with proof beyond all reasonable doubt that our leaders are Satanic pedophiles who were Saudi control and secretly building a rogue nuclear state in North Korea would very much cause a mental health crisis in these brainwashed people. Finding out that everything they've known in their entire lives is a lie would destroy them.
