Anti-semitism doesn’t just come from the Right. Or of the Left. Or blacks. Or whites. Or Christians. Or Muslims.
“If the long, bitter history of anti-Semitism teaches anything, it is that “the oldest hatred” can take any shape and adapt to any ideology. Nazis or Communists, Christians or Muslims, Trump backers or Trump foes, white extremists or black extremists — hostility to Jews grows in any soil. And if you condemn anti-Semitism only when it comes from the team you oppose, you haven’t condemned a thing.
Jew-hatred thrives where Jew-haters are tolerated: Therefore they must not be tolerated. For most of the postwar decades, a powerful taboo made anti-Semitism largely intolerable. But that taboo is breaking down, and Jews are again endangered. Even in America, where that was once unthinkable.
