“In every generation there are those who rise to annihilate us”: This is one passage in the Haggadah that Jews have been reading this week as they celebrate Passover. If they live near New York’s Columbia University, or any similar campus, all they need as proof is the hum from outside. Pro-Hamas fans of Hezbollah and Osama bin Laden, and other haters, blame Jews, or in this case the Jewish state, for every ill under the sun.
