At the centre of radical left antisemitism is its theory of racial oppression. The radical left holds anti-racism as a core principle and conceives of oppression through a binary of oppressors v oppressed, of whiteness v people of colour. It is a theory that has many merits, but when applied to Jews it becomes a quagmire of prejudice.
Put simply, the student left conceives of Jews as white. Sephardi and Mizrahi Jews are ignored and the history of Jewish oppression through racial construction is dismissed, with Jews framed as the oppressors and the beneficiaries of white privilege. The perception carries weight because in the eyes of many, it contains some truth. The argument that Ashkenazi Jews benefit from white privilege is not uncommon, nor is it restricted to the radical left.
Yet the consequence of seeing Jews as white is in effect antisemitic. Jews are identified with power, privilege and oppression, leading to overtones of some of the oldest antisemitic tropes: Jews controlling politicians, the media and financial institutions.
By seeing Jews as white oppressors, the student left also vaccinates itself against any sort of sympathy for the Jewish experience. Unsurprisingly, this manifests itself in anti-Zionist politics. The radical left interprets Israeli politics through the “settler-colonial” paradigm. Not only does it take a quite incredible lack of compassion to see a Jewish holocaust refugee as a skull-capped Cecil Rhodes, it is no coincidence that Jews are seamlessly aligned with white colonialism – the radical left’s highest manifestation of whiteness, power, and oppression.Source
One of the reasons I try and avoid using the term "white", preferring the term "European" instead, is that avoids ridiculous debates like "whether Jews are white". Of course Jews are happy to describe themselves as white when it suits them, usually when they are calling for the immigration floodgates to be open: "Trust me, fellow white people, it will be fine."
