In Politico, Jeff Greenfield actually has a piece titled “The Ugly History of Stephen Miller’s ‘Cosmopolitan’ Epithet”, in response to Stephen Miller saying Jim Acosta displayed a “cosmopolitan bias”. Greenfield writes:
Why does it matter? Because it reflects a central premise of one key element of President Donald Trump’s constituency—a premise with a dark past and an unsettling present.
So what is a “cosmopolitan”? It’s a cousin to “elitist,” but with a more sinister undertone. It’s a way of branding people or movements that are unmoored to the traditions and beliefs of a nation, and identify more with like-minded people regardless of their nationality…
I’m waiting for it… waiting… it’s gonna come. It’s definitely gonna come.
One reason why “cosmopolitan” is an unnerving term is that it was the key to an attempt by Soviet dictator Josef Stalin to purge the culture of dissident voices. In a 1946 speech, he deplored works in which “the positive Soviet hero is derided and inferior before all things foreign and cosmopolitanism that we all fought against from the time of Lenin, characteristic of the political leftovers, is many times applauded.” It was part of a yearslong campaigned aimed at writers, theater critics, scientists and others who were connected with “bourgeois Western influences.” Not so incidentally, many of these “cosmopolitans” were Jewish, and official Soviet propaganda for a time devoted significant energy into “unmasking” the Jewish identities of writers who published under pseudonyms.
There we go.
To be clear: Steve Bannon and Stephen Miller would angrily wave away any suggestion that they are echoing the sentiments of anti-democratic political movements, much less anti-Semitic dog whistles. But there is no evading the unhappy reality that to label someone a “cosmopolitan” carries with it a clear implication that there is something less patriotic, less loyal … someone who is not a “real American.”
So, describing someone’s liberal immigration philosophy as ‘cosmopolitan’ is anti-Semitic.
