You're not a Zionist, but you then proceed to make a Zionist argument?

The Palestinians were the only people living on the land before the settlers came. That included Jews and Christians, because Palestinians are not a homogeneous group.

The Zionist settlers are not indigenous, they had no right to settle there. They also took the UN resolution and just started a war where they razed 500 villages. I'm sure if the Palestinian side had won, they would have expelled the settlers. But that is only natural. And beside the point, because the Palestinians didn't start the war, and of course uou expel invaders.
