That is another misconception, if we are advocating the native people who did not convert to leave, than their won't be any palestinian, christian, Jews, in the contrary their are, and has and do exist. We are not against Jew's but the the Zionist state and the people who forcefully took people lands, livelihood with murder and rape of the land that never was theirs and setting up a state.
We are not saying the native Jews or christian to leave, unless you think they never existed. You must note that not all Jews in Israel are native but was immigrated to push up the population so they can set up a majority of goverment and a state on other peoples land which been forcefully stolen.
Is simple, what if Indian comes into britian, expel the native people out of their home and land (stealing it) and set up a state of their own state here in britain with Indian being the Majority.
OF course you will fight against those indian that took your home, in the cost of the blood of your women and childre, and you won't recognise their Indian state and their right to exist.
