Some of the shortcomings and rather outrageous aspects of this story are encapsulated by the letter the American Jewish Committee (AJC) wrote to Macmillan. Among the points made by the AJC and other critics are.
1. No other form of nationalism is included in the three-volume encyclopedia. Only Jewish nationalism is addressed. That should immediately raise a red flag.
2. Noel Ignatiev has absolutely no track record of scholarship in Middle Eastern or Jewish studies. He has described Zionism as an "ideology of race" and scandalously promotes the canard of Zionist-Nazi "collaboration." This is hardly an impartial article on Zionism in what is supposed to be reference work.
3. In fact Ignatiev wrote a very similar article which appear on Counterpunch, a site known for its anti-Zionism and anti-Israelism [opposition to the existence of the Jewish state not just to its policies].
4. Apparently when the AJCommittee contacted Macmillan for an explanation John Hartwell Moore, the encyclopedia’s Editor in Chief, defended the entry by arguing that Jewish nationalism is racist because it’s Jewish.
5. In his earlier statements and in the article conflates Zionism and Nazism. Ignatiev claims that Zionism “shared the [Nazi] belief that the Jews were a racial community based on blood.” This. of course, is complete balderdash, if not worse. Zionism says nothing about Jews being a racial community based on blood. This is Nazi talk and has nothing to do with Zionism.
6. Since the author is known as a propagandist -- not a scholar -- opposed to Zionism. As Brian Henry, a Canadian author, has asked "If the editor concerned chose Ignatiev because of his prejudices, how many other entries in the encyclopedia might reflect the editor’s political agenda?"
There is an excellent in depth critique of this whole shameful episode here.
