• Doublethink

"Doublethink is a process of indoctrination in which subjects are expected to simultaneously accept two conflicting beliefs as truth, often at odds with their own memory or sense of reality. Doublethink is related to, but differs from, hypocrisy."

Edited to add:

It's a common tactic with fascist regimes. Nazis used to do it with Jewish propaganda by simultaneously claiming that Jews were weak vermin that needed to be exterminated and that they are this supervillain that controls all the money.

You currently see it a lot with the people chanting "Genocide Joe" and claiming he is some mastermind warhawk with at the same time claiming that he is some feeble, senile old man. He's Schrödinger's politician!
