This is a problem because the Passover dinner has an important portion dedicated to a statement that has been made by Jews every year for 2,000 years. That is a statement made more than a billion times by Jews. 'Next year may we be in Jerusalem!'
I have a bias in this matter. When I was in Israel in 1958 and 1959 the Arabs would not permit me, any Jew, any Israeli or any American to enter 3/4ths of Jerusalem and especially the Old City that was founded and built by David and Solomon.
I'll never forget that any more than I'll forget the Shoah and European Jew -hatred.
Maybe there is a conflict between having voted for Obama and calling yourself a Jew.
