There is a Kurt Vonnegut novel called Mother Night that's a morality tale about this exact propaganda tactic. The character in that novel pretended to be a Nazi media personality whose plan was to wake up the masses by saying the most over-the-top, bat shit crazy things that no one could possibly agree with. It totally backfired and no matter how absurd he made it, people went along with it wholeheartedly. Turns out the sheep have no bullshit sensor in their brains in the first place. So they'll go along with whatever they perceive to be the norm. Neighborhood street gangs FTW. Moral of the story: Be careful what you pretend to be.
