This essay coins a term “Judeopessimism,” engaging questions of some of the contemporary writing on antisemitism and its claim to be historical in nature through the lens of critical race theory, specifically Afropessimism and its offshoots, which make claims of anti-Blackness as political ontology. Is some of this writing on antisemitism really making theological or political ontological claims of “eternal antisemitism” refracted in a less volatile historical narrative? How can critical race theory and its understanding of anti-Blackness help refine, clarify, and push the discussion on antisemitism to be more forthright about its underlying claims? I explore some examples of ontological antisemitism in the writings of Meir Kahane and Naftali Zvi Berlin who each in different ways offer ahistorical and even ontological views on antisemitism that are mostly shunned by contemporary writing on the subject and suggest that Afropessimism offers a helpful way to see beyond the historical veil of how antisemitism is understood today.
