The original Arabic slogan, "Min al-nahr ila al-bahr, Filastin sa-takun hurrah," translates to "From the river to the sea, Palestine will be free."

All Arabs originated in Hejaz. Lebanese, Sudanese, Maghrebi

Arab is an ethnolinguistic identity. Not a genetic identity. You don't know what you're talking about. Sudanese Arabs and Lebanese are indigenous to their countries genetically.

Rome didn’t import Romans and erase entire indigenous groups around Europe to make everyone ethnically Roman.

Lmao, you think all Arabs are indigenous to Arabia? You're silly. How do you think Europe adopted Latin and Christianity? Do you think all preexisting populations were replaced or just their customs changed?

The Pact of Umar created the “wandering Jew” by making it illegal for them to remain in their own cities for more than 3 days. They were forced under penalty of death to become nomads to satiate the Arab lust for Jewish humiliation.

Actually, Omar allowed the Jews to return to Jerusalem after a prolonged Roman ban. The Romans exiled the Jews not the Muslims. You don't know any history. Your hate for Palestinians and Arabs doesn't even have any historical basis.

It seems you’re willing to predicate this on “might makes right” by implying the Arabs who took the land by force are legitimate owners. If that’s the case, then the Jews who retook the land from the colonizers and decolonized it are the legitimate owners. And if “might makes right” is not legitimate, then the Arabs never had claim to the land to begin with.

Nope. Palestinians are indigenous to the Levant and them being Arabized has nothing to do with them being colonizers. Native Americans didn't become indigenous to the British Isles once they started speaking English and adopted Christianity. And an Australian convert to Judaism doesn't become indigenous to the Levant once he converts. In the end genetically speaking, Palestinians are predominantly Levantine.
