Zionists are not following Judaism. If you ask jewish people living in occupied Palestine they’ll tell you they are in exile and are not allowed to have their country until the arrival of the Messiah, that they are simply living in that land that belongs to whoever ot belonged to.
Zionists om the other hand are imperialist colonisers who took the land from its owners. So asking for the land to return to its rightful owners is legitimate, and this translates to the end of the existance of the state created on wrongfully seized land.
So, per your words, jewish people are zionists who use religion as an excuse to occupy a land that is not theirs (and keep expanding with more settlers every chance they get). Also, isn’t israel supposed to be their god given country? Why would they leave?
