Book excerpt: David didn’t defeat Goliath with a tennis racket. In The Wrong Jew, author Hesh Kestin doesn’t bother with the why of anti-Semitism but instead offers a battle plan for how to defeat those who would destroy the Jews. At a time when Jews are under attack from right and left, posting guards around synagogues is hardly the answer. Just as Israel takes the fight to its enemies, Kestin explains how American Jews must go on the offensive by teaching our kids to speak up and our adults to use our financial, legal, and political resources to make life miserable for Nazis of every stripe. According to Hesh Kestin, “When they pick on American Jews, let them learn they picked on the wrong Jews.”
