Maybe the demographics of Palestine region can help: https://en.wikipedia.org/wiki/Demographic_history_of_Palestine_(region)
There were just 2.000 Jewish people left in Palestine in the 17th century. End of 19th century there were like 40k of them, when the Jewish Colonial Association started with the massive organized colonization of the region. So, by 1947, Palestine ended up with around 600k+ Jews, the vast majority of them, obviously Zionists.
There argument is really, that 2000 years ago, they were the majority in the region, therefore everyone calling themselves a Jew today, is considered "native" to Palestine.
Many "scratched libs" were screaming at me how "Hamas is looting humanitarian aid", so the genocide must continue...I am looking forward to rubbing this into their faces ad nauseam. Will let you know the results.
