On May 11, masked hooligans surrounded a synagogue in Brooklyn, shoved congregants, and blocked them from entering. Just a few days before, keffiyeh-clad thugs rushed police barricades protecting a Manhattan synagogue. In April, a similar crowd harassed Jewish diners sitting at sidewalk tables. Ever since October 7, 2023, in fact, cities, towns, and campuses across America have been periodically overrun by such hoodlums.
