It all comes down to breaking away from reality. The more you break away from reality, the further you have to drift away to keep making sense. Delusion feeds on itself. Once you get someone to depart from reality, even a little bit, it becomes a feedback loop.

This is the same technique used by BLM, Trans agenda etc. The moment you agree "there is White privilege" or "men are women" you are departing from reality. Then you will just twist everything around you to fit this narrative.

However, at the very time, you are not invested in the lie. You might say "Men are women" to please your teacher / friends, but next time you see something incongruous you ditch that idea. The key is to get the person to be invested in the lie.

How do you do this? Use their insecurities. If they crave approval from others, put peer pressure ("we dont hang out with racists"). If they are insecure about their goodness, make it a virtue ("if you believe this, you are a wonderful person"). If they are insecure about their brains, make it an intellectual issue ("All the smart people are saying this"). and so on.

So insecurities + departing from reality = delusion.

Mass delusion + fear = Mass psychosis

Mass psychosis = anything you want.

There is only one way to cure insecurities. You have to learn to love yourself for who you are. This is where God comes in. If you believe that you are a creation of God, you will love yourself unconditionaly. If not, you will try to "prove" yourself worthy of love - and that is what leads to insecurities.
