As organizations that care deeply about the State of Israel and about the wellbeing of the Jewish people, we are deeply committed to the struggle against antisemitism. We are thus obligated to share our concerns about ways in which the effort to combat antisemitism is being misused and exploited to instead suppress legitimate free speech, criticism of Israeli government actions, and advocacy for Palestinian rights. In particular, the effort to enshrine in domestic law and institutional policy the International Holocaust Remembrance Alliance (IHRA) Working Definition of Antisemitism, with its accompanying “contemporary examples,” risks wrongly equating what may be legitimate activities with antisemitism.
