Yet such hostility between groups has at times drawn on some of the rhetoric of antisemitism: "criticism of subgroups of Jews which drew on anti-Semitic rhetoric were common in 19th and 20th century arguments over Jewish identity". In practice, according to one academic, whilst there have been Jewish writers in the late 19th and early 20th centuries who consistently employed virulent antisemitic rhetoric without seeming to value any aspects of being a Jew, too often "those who accuse others of being self-haters search for examples of when they have criticized Jews or Judaism but ignore examples of when those they criticize have shown they value being a Jew." He argues that Jewish antisemitism does not necessarily amount to self-hatred, implying that "antisemitic Jew" may be a more accurate term to use. Other authors have also shown a preference for using "antisemitism" rather than "self-hatred."
