Butler is providing justification so her followers can shout Nazi at anyone who disagrees. It needs to be fancily phased to fool the stupid but simple enough that bits can be repeated on twitter. Anything more is inefficient.
In Hannah Arendt's 1963 book Eichmann in Jerusalem , she describes Adolf Eichmann as a pseudo-intellectual who used clichés and platitudes as sufficient explanation and justification of his actions. Among her interrogation of what this means for philosophy, she outlines that these pre-packaged phrases are offered up as a simulacrum of thought and indicate thoughtlessness as an absence of thought. Arendt wrote:
"When confronted with situations for which such routine procedures did not exist, he [Eichmann] was helpless, and his cliché-ridden language produced on the stand, as it had evidently done in his official life, a kind of macabre comedy. Clichés, stock phrases, adherence to conventional, standardized codes of expression and conduct have the socially recognized function of protecting us against reality, that is, against the claim on our thinking attention that all events and facts make by their existence."

Given that JB has written about Arendt and Eichmann in the past, it feels very odd that she is not seeing the linguistic similarities for herself nor recognising just who it is who is nudging society towards mumbling clichés as a sufficient explanation and justification of authoritarianism.
