Abstract
Notwithstanding the increasing alignment between social and political identities, political divisions exist within social groups as well as between them. Despite their shared traditions, American Jews face similar political divisions as Americans in general. But could the perception of a common threat, such as antisemitism, alter the dynamics of political polarization within a social group? American Jews' concerns about antisemitism might themselves be filtered through political identities, with liberal Jews more concerned about "traditional" antisemitism (long-standing anti-Jewish stereotypes) emanating from the political right, and conservative Jews concerned about "Israel-related" antisemitism (blaming individual Jews for the actions of Israel) associated with the political left. Using a sample of over 2000 Jewish young adults, we find that, although liberal and conservative Jews are equally concerned about traditional antisemitism, conservatives are significantly more concerned about Israel-related antisemitism than liberals. We also find that, after a series of high-profile attacks on American Jews related to the 2021 Israel-Hamas conflict, liberal and conservative Jews' concerns about Israel-related antisemitism increased at similar rates. These results suggest that, although concerns about antisemitism are influenced by political identity, rising antisemitism is unlikely to exacerbate political polarization between liberal and conservative Jews.
