Anti-Zionism is more dangerous than anti-Semitism, threatening lives and peace in the Middle East.

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.
