There's a thin line between Anti-Semitism and Anti-Zionism. That's true of Muslims and the left, but it's also true specifically of the Jewish left, whose hatred for Israel manifests itself in a general contempt for Jewish religion, culture and tradition.
Take the Jewbags case of Danielle Gilbert, a staffer for Democratic National Committee chairwoman Debbie Wasserman-Schultz who had been appointed the DNC's Jewish outreach liaison. In a social media mishap, Gilbert posed along with her friends in a photo that she captioned "JEWBAGS" and that a friend of hers captioned as "Jew cash money team."
