The Muslims and Christians that live in Palestine are mostly descended from the Jews that lived in the Levant, it's not like literally everyone was expelled. There's a reason Israel doesn't require a DNA test to determine if someone is actually descended from people from the Levant, there's a reason Israel has some of the highest skin cancer rates in the world (on par with other white settler colonies like Australia), and there's a reason they pretended Palestine was "a land without a people for a people without a land."

They're white colonizers stealing land. They don't have any right to take it, they can either become Palestinian or go back to Europe.

There were people there, and they have a right to the land. Europeans can move there and join a single multi-ethnic, multi-racial, multi-religious democracy where Jews live with everyone else. They don't need to steal land from people already living there, they don't get to make a nation where Jews have special rights and everyone else is second class, they don't get to have apartheid.
