zionism is the belief that the jews have the right to live in their ancestral homeland (ancient judea), which is not at the expense of anyone else.
any jew that's gone on birthright visits Masada, it's a right of passage. the vast majority of jews around the world are zionist and believe israel is the original homeland of jews, which historically is true.
now if there's an argument to be made that there should be no religious centric nations, well then we should hold the christian and muslim majority states to the same standard, no?
