Which group of people is targeted for mistreatment by followers of anti semitism?

The answer is the Jews.  During the entry of the US into the World War I, they were targeted by anti-semites as "slackers" and "war-profiteers" accountable for many of the ills of the country. For instance, a U.S. Army manual printed for war recruits stated that, "The overseas born, and especially Jews, are more suitable to shirk than the native-born." When ADL representatives complained about this to President Woodrow Wilson, he ordered the manual recalled. The ADL also on a movement to give Americans the facts about military and civilian contributions of Jews to the war effort.
