If there is, indeed, any such thing as a “New Anti-Semitism”, it is “new” in the sense that it does not fit the historical pattern of ancient anti-Semitism, which was primarily cultural in nature; Christian anti-Semitism, which was religious; and modern anti-Semitism, the racial variety of the 19th and 20th centuries, which culminated in Nazism and ultimately in the destruction of European Jewry. Finally, there is the contemporary manifestations of anti-Zionism and Israelophobia, and how they fit (or don’t fit) the pattern.
