And, regarding history, stop being obtuse about who was originally on that land.
Oh you mean the Assyrians or Phoenicians or whichever other ancient people were there before the Jews.
Why didn't you make that clear in the first place.
The Palestinians were not there, as such, until much later.
You have one point - people did occupy the area when the Jews began returning. Some were Jewish "Palestinians" and some were Islamic "Palestinians" (of diverse racial ancestries - remember that a lot of "Frankish" ancestry entered the region during the crusades)
The initial land acquisition after the British took the region from the Ottomans, was by purchase. During that time an idiotic British governor got the idea to call it a crusade, not realizing that the locals viewed the term as akin to genocide by Europeans.
Fairness indicates that the Palestinians who were occupying land that became Israel in 1948, along with their children, should have the option of being Israeli citizens. But all the rabble who swarmed into the country later need not be given that option; they can be asked to go back to whence they came.
The edge case is the children of latter emigres who have no such claim, but have no other place. Further muddying the water is the ongoing attempt to destroy Israel. Violence began as early as the 1930's (or perhaps before) based solely on antisemitic rhetoric and bigotry. Some of those criminals helped found the Palestinian Liberation movement, and hence reduce its legitimacy. Particularly since Palestine did not exist as an independent state in the 1930's - it was spoils of war won from the Ottomans.
Certainly a narrow minded racist like you has no grounds to judge who should be allowed to remain and who should be forced to leave.
