I can answer this question as I have been doing and will continue to do: antisemitism fuels White nationalism, a genocidal movement now enthroned in the highest seats of American power, and fighting antisemitism cuts off that fuel for the sake of all marginalized communities under siege from the Trump regime and the social movement that helped raise it up. To refuse to deal with any ideology of domination, moreover, is to abet it. Contemporary social justice movements are quite clear that to refuse antiracism is an act of racism; to refuse feminism is an act of sexism. To refuse opposition to antisemitism, likewise, is an act of antisemitism. Arguably, not much more should need to be said than that. But I suspect that much more does need to be said. To the hovering question, why should we be talking about antisemitism, I reply, what is it we are afraid we will find out if we do? What historic and contemporary conflicts will be laid bare? And if we recognize that White privilege really is privilege, what will it mean for Jewish antiracists to give up the fantasy that they ever really had it to begin with?
