Orwell's work was peak english literary culture, and what they call criticim and theory are really just a way to dissolve meaning and kill culture by preventing it from persisting as coherent meaning in time. It's an unmooring and uprooting, and it does not produce anything anyone actually desires other than a set of shibboleths for a conspiracy to destroy a culture and rule over its ashes.

There is no political-right, it is an artifact of whatever these people are criticizing to destroy and rule over the ashes of, it means nothing. Specifically, it uses ideology to assign or project an othering counter-ideology on its enemies to manage them with further criticism. It's mesmerist gibberish all the way down.

That we need words at all to describe it is a fairly modern invention, because historically it was just evil trying to dissolve your society and enslave it, everyone saw it, and you just smote it for what it was.

In their own words, suffocate it from the oxygen of attention it needs to survive.
