Why Are Most Jews Liberal?

Dennis Prager explains it here

Excerpt:

Liberal Jews fear nationalism. The birth of nationalism in Europe planted the secular seeds of the Holocaust (religious seeds had been planted by some early and medieval Church teachings and reinforced by Martin Luther). European nationalists welcomed all national identities except the Jews'. That is a major reason so many Jews identify primarily as "world citizens"; they have contempt for nationalism and believe that strong national identities, even in America, will exclude them.

Just as liberal Jews fear a resurgent Christianity despite the fact that contemporary Christians are the Jews' best friends, leftist Jews fear American nationalism despite the fact that Americans who believe in American exceptionalism are far more pro-Jewish and pro-Israel than leftist Americans. But most leftist Jews so abhor nationalism, they don't even like the Jews' nationalism (Zionism).
