Unlike a dictatorship, the head of a totalitarian regime is an ideology. That makes it very hard to end the regime by simply toppling its titular leader. You must discredit the ideology or subsume it with another one.
The Left is highly motivated by fear, and they fear a world in which they are not in control they will be victimized by those who are. This is driven by the Marxist belief that all power imbalances between people result in a oppressor/oppressed relationship.
Orwell got a lot of things right, like the surveillance state and doublethink. How close was his vision of the geopolitical landscape in 1984 to real life?
You're meant to fear black shirts kicking down doors and beating people who go against the regime, but what the Left really seems to fear is that she'll be successful in delaying or halting their Great Reset plans. More than jackbooted thugs, the Left fears Meloni's ability to stifle their agenda to establish a global, collectivist oligarchy.
Postmodernism is a philosophy that refutes the notion of objective reality. It refutes the Enlightenment notion that Man advances his situation mainly though reason. Enlightenment philosophies are the basis of modern Western democracies in general, and of the United States in particular. Enlightenment thinking stands in the way of establishing a collectivist Utopia, and so must be supplanted in the body-politic by the post-modern viewpoint. Postmodernism can be said then, to be the philosophic means to that collectivist end.
The left's assault on the English language continues, most recently with their attempt to redefine the word "infrastructure". "Control the language and you control the debate," is an axiom in the worlds of politics, the law, and anywhere else where influencing thought is considered valuable. The left, being well aware of this has been working for decades redefining words. Terms like racist, fascist, and justice have been so far removed from their meanings as to become unrecognizable to those of us who know the original, correct definitions.
