In a modern, democratic world, of which Israel claims to be a part, every citizen is free to practice any religion they choose - or not as the case may be. Jews exist as followers of Judaism. Drop the religion and you are not Jewish. Moslms exist as followers of Islam - drop the religion and you are not Moslem. Palestine will be a palestinian state just as Israel is an Israeli state. These are nationalities. Most Jews do not live in Israel and do not want to. Religiously defined states are backward.
