The holocaust is a normie foundation myth that could almost be classified as a religious belief at this point. It's a priori and can not be questioned. So you really don't want to drop it on them as your first pill. I agree that it will cause too much cognitive dissonance in the average NPC and they will vomit up the pill and lash out.
That being said I'm in that camp that believes we will never be able to buck the pervasive jewish control of media and banking without a mass awakening to the holohoax. Without breaking people out of that conditioning you can't really get them to understand the gravity of the situation we are in. Jewish mind controllers crown jewel weapon is white guilt and the holocaust is the ultimate white guilt. Break that and we win. Smash the jews best weapon and we secure a future for our people.
