Recent criticism of Women’s March activists Linda Sarsour and Tamika Mallory over accusations of antisemitism have caused a new round of moral manic about left-wing antisemitism. Eric Morgenson recounts a similar episode from the 1980s when Jesse Jackson faced criticism over Israel and his association with Louis Farrakhan: “If the Jewish community’s experiences with Jesse Jackson in the 1980s teaches progressives anything, it should be that accusations of antisemitism can be weaponized to de-legitimize those on the left, especially people of color.”
