1) Some anti-Zionist Jews argue that Judaism and Zionism are fundamentally incompatible because Judaism is a religion and moral tradition, while Zionism is a political nationalist movement. They believe that Jewish identity should be based on faith, ethics, and community rather than support for a nation-state.
2) Certain religious groups, such as Neturei Karta, argue that Jewish teachings forbid the creation of a Jewish state before the coming of the Messiah, making Zionism a violation of Judaism itself. Others oppose Zionism because they believe the treatment of Palestinians contradicts Jewish values of justice and compassion. From this perspective, a person cannot fully uphold Jewish principles while supporting Zionism, and therefore a Zionist cannot be a Jew, and a Jew cannot be a Zionist.
2) From their perspective, creating a new denomination that combines the two would not solve the contradiction, because they believe the issue is foundational: Judaism is meant to center faith, morality, and covenant with God, while Zionism centers statehood and nationalism. Therefore, they argue the two remain incompatible regardless of denomination.
