According to Amos Elon, during 19th-century German-Jewish assimilation, conflicting pressures on sensitive and privileged or gifted young Jews produced "a reaction later known as 'Jewish self-hatred.' Its roots were not simply professional or political but emotional." Elon uses the term "Jewish self-hatred" synonymously with Jewish antisemitism when he points out, "One of the most prominent Austrian anti-Semites was Otto Weininger a brilliant young Jew" who "published 'Sex and Character', attacking Jews and women." Elon attributes Jewish antisemitism as a cause in the overall growth of antisemitism when he says,"(Weininger's) book inspired the typical Viennese adage that anti-Semitism did not really get serious until it was taken up by Jews."
