Left-Wing Antisemitism, Academic Ideological Bias, and the Post-October 7 Crisis: A Critical Analysis of Brazil and the Global Discourse

**The Hamas terrorist attack of October 7, 2023—**the deadliest assault against Jewish people since the Holocaust—triggered a global wave of antisemitism that exposed deep-seated ideological biases within academic institutions, progressive political movements, and international media. This paper conducts a critical, interdisciplinary analysis of the phenomenon of left-wing antisemitism as it manifested in Brazil and comparable Western democracies in the aftermath of October 7. Drawing on political theory, historical analysis, media studies, and documented incidents, we examine how decolonial theoretical frameworks, oppressor–oppressed ideological binaries, and institutional power dynamics within universities have facilitated the normalization of antisemitic discourse under the guise of anti-Zionism. We further investigate the diplomatic rupture between Brazil and Israel, precipitated by President Luiz Inácio Lula da Silva’s inflammatory Holocaust comparisons, and the structural conditions—including academic ideological conformity and media framing biases—that enabled such rhetoric. The paper argues that selective outrage, the silencing of dissenting academic voices, and the instrumentalization of identity politics frameworks constitute a modern form of left-wing antisemitism with measurable consequences for Jewish communities worldwide. We conclude with reflections on the responsibilities of universities, media organisations, and political actors to uphold epistemic integrity, historical accuracy, and moral consistency in their treatment of antisemitism and the Israeli–Palestinian conflict.
