This is quite possibly the worst piece of scholarship that I have read in this field. The central conceit of the book involves an error of self-persuasion: namely, that the author's own vicissitudes over racial issues in the post-60s decades are historically reflected in some empirical fashion in the history of Jewish people in American society. The insights that the author has lifted from other books are of the cut-and-paste variety rather than a serious rethinking and analysis.
