Jews and dating
Rosenfeld takes "a hard look at Jewish authors" whose statements go well beyond "legitimate criticism of Israel," and considers rhetoric that calls into question Israel's "right to continued existence" to be antisemitic.
In English the first major discussion of the topic was in the 1940s by Kurt Lewin, who was Lessing's colleague at the University of Berlin in 1930.
"Within the logic of the concept, those who accuse others of being self-hating Jews may themselves be self-hating Jews." The specific terms "self-hating Jew" and "Jewish self-hatred" only came into use later, developing from Theodor Herzl's polemical use of the term "anti-Semite of Jewish origin", in the context of his project of political Zionism.
The underlying concept gained common currency in this context, "since Zionism was an important part of the vigorous debates that were occurring amongst Jews at the time about anti-Semitism, assimilation and Jewish identity." He was referring to "philanthropic Zionists", assimilated Jews who might wish to remain in their home countries while at the same time encouraging the Jewish proletariat (particularly the poorer Eastern Jews) to emigrate; yet did not support Herzl's political project for a Jewish state.
It was the Rosenfeld essay, which did not use the term Jewish self-hatred, that led to the 2007 debate.
Critics claimed the charge of antisemitism implied Jewish self-hatred to those criticizing Israel.
