This isn't Reddit. Many people here actually do read sources. All the censuses in the decades before the fall of the Ottoman empire show a Jewish majority. And for the century preceding that, the censuses flipped back and forth.

No. The UN designated the malaria-infested marshes Israeli (not Jewish) and the majority of the rest Arab (not Muslim, not Palestinian, and not Egyptian or Jordanian). The Arab states rejected this, and opened a war with the newly formed Israel. Many Israeli leaders pleaded with the Arab residents not to heed the Arab states' calls to evacuate. The situation in Haifa is well documented, I know this from living with Arabs in Haifa two decades ago. They tell how the Haifa mayor pleaded with their families to remain in 1948.
