There are native people to the land who are Jewish. That does not mean that all Jews globally are native to Palestine or that only Jews are native to the land.
There are still some Celts in continental Europe (mostly in Brittany). So thus the Irish, Scottish, Cornish, Welsh, Manx, and such are all totally justified in settling and displacing everywhere their ancestors have ever lived, right?
So if you could imagine the British not allowing celts in England. Don’t you know? The Celts settled the British Isles and Ireland and displaced the people living there in the iron age
