Judea Pearl, a professor at UCLA and the president of the Daniel Pearl Foundation, wrote the following in an LA Times Opinion Piece. Here are some key excerpts:
Anti-Zionism rejects the very notion that Jews are a nation -- a collective bonded by a common history -- and, accordingly, denies Jews the right to self-determination in their historical birthplace. It seeks the dismantling of the Jewish nation-state: Israel.
Anti-Zionism earns its discriminatory character by denying the Jewish people what it grants to other historically bonded collectives, namely, the right to nationhood, self-determination and legitimate coexistence with other indigenous claimants.
Anti-Semitism rejects Jews as equal members of the human race; anti-Zionism rejects Israel as an equal member in the family of nations.
Are Jews a nation? Some philosophers would argue Jews are a nation first and religion second. Indeed, the narrative of Exodus and the vision of the impending journey to the land of Canaan were etched in the minds of the Jewish people before they received the Torah at Mt. Sinai. But, philosophy aside, the unshaken conviction in their eventual repatriation to the birthplace of their history has been the engine behind Jewish endurance and hopes throughout their turbulent journey that started with the Roman expulsion in AD 70.
Given this understanding of Jewish nationhood, anti-Zionism is in many ways more dangerous than anti-Semitism.
First, anti-Zionism targets the most vulnerable part of the Jewish people, namely, the Jewish population of Israel, whose physical safety and personal dignity depend crucially on maintaining Israel's sovereignty. Put bluntly, the anti-Zionist plan to do away with Israel condemns 5 1/2 million human beings, mostly refugees or children of refugees, to eternal defenselessness in a region where genocidal designs are not uncommon.
Secondly, modern society has developed antibodies against anti-Semitism but not against anti-Zionism. Today, anti-Semitic stereotypes evoke revulsion in most people of conscience, while anti-Zionist rhetoric has become a mark of academic sophistication and social acceptance in certain extreme yet vocal circles of U.S. academia and media elite. Anti-Zionism disguises itself in the cloak of political debate, exempt from sensitivities and rules of civility that govern inter-religious discourse, to attack the most cherished symbol of Jewish identity.
Finally, anti-Zionist rhetoric is a stab in the back to the Israeli peace camp, which overwhelmingly stands for a two-state solution. It also gives credence to enemies of coexistence who claim that the eventual elimination of Israel is the hidden agenda of every Palestinian.
It is anti-Zionism, then, not anti-Semitism that poses a more dangerous threat to lives, historical justice and the prospects of peace in the Middle East.
