"Elon Musk has shown a refusal to back down from the danger he poses to Jews and other minorities and vulnerable communities. Appealing to him directly, as the ADL and others have, has been an abject failure. Outside pressure that hits him where it hurts is the only effective measure. Not doing so will mean the further spread of extremism and antisemitism. Those don’t just threaten Jews: they threaten a free society and all those affected by the conspiracy theories tied to antisemitism."
