The two of us have been having the exact same conversation for the past decade. About anti-Semitism and us have been having the exact same conversation for the past decade. About anti-Semitism and Islamophobia . One of us a Muslim, the other a Jew, we have conducted it in public and in private, on Twitter and on TV. We’ve agreed; we’ve argued; we’ve even wandered off topic to trade tips on how to get through a fast. Now we’ve come together because of the urgent and common threat that we face. Both of our communities are under violent attack from far-right white supremacists. In Christchurch, New Zealand, last month a white supremacist gunned down 50 Muslims at prayer. In Pittsburgh, Pennsylvania, last October a white supremacist gunned down 11 Jews at prayer. Both killers were clear in their loathing of both Jews and Muslims. Both subscribed to the “great replacement theory,” which casts Muslims and other minorities as “invaders” of Western societies and a threat to white, Christian majorities. In this narrative, the supposed invasion is a wicked plot orchestrated by the same hidden hand behind all malign events through world history: the Jews. The point was put concisely in an online remark reposted by the Pittsburgh murderer: “It’s the filthy EVIL jews Bringing the Filthy EVIL Muslims into the Country!!” This is how our haters see us: Jews and Muslims connected in a joint enterprise to effect a “white genocide.” It is an unhinged and racist conspiracy theory — and it has both of our communities in its murderous sights. So there can only be one response: Muslims and Jews must stand and fight it together.

This is how our haters see us: Jews and Muslims connected in a joint enterprise to effect a “white genocide.” It is an unhinged and racist conspiracy theory — and has both of our communities in its sights.

Both the Muslim who hates Jews and the Jew who hates Muslims forget that the white supremacist hates them both.
