Conservative Movement in Israel CEO Yizhar Hess last week called the proposal “madness.”

“We never imagined,” he said in a statement, “that this government would support such a post-Zionist act. This bill says to the vast majority of Jews in Israel and the world that they are not Jewish.”

Rabbi Gilad Kariv, head of the Reform movement in Israel, said last week that the proposed legislation was ultra-Orthodox incitement against Reform Jews. “It is terrifying to see that instead of condemning the death threats that the heads of the Reform Movement received in the past few days, the head of Shas continues to incite divisiveness and hate.”

Both Hess and Kariv called on Netanyahu to torpedo the bill, the Ynet news site reported.
