The president has been ranting about globalists. I did some research into why the "globalist" label is considered anti-semitic, and what it means to be a globalist, anyway. And then I wrote an essay for the Forward, and here's a taste:
...The connection between globalists and Jews is, in part, the old anti-Semitic smear that Jews are not truly loyal citizens of any nation. Hitler described Jews as “international elements” that “conduct their business everywhere,” thus harming and undermining good people who are “bound to their soil, to the Fatherland.” Use of globalist as a negative term can be a dog whistle for the far right: those who recognize its roots in Hitler’s philosophy recognize that it’s an encoded way of denigrating Jews.
Some people speak interchangeably of globalism and cosmopolitanism. I absolutely identify as a cosmopolitan — someone who aspires to be a citizen of the wide world, with an awareness that in an interconnected community, we have ethical obligations even to people who live differently than we do... So does that mean I’m a globalist, too?...
(Spoiler: yes. Yes, I am, and proudly so -- and I believe that Judaism demands no less, and I wouldn't want to be otherwise.)
