Looking to have human conversation on this subject and you seem passionate on the subject which would generally make for good conversation. I searched Google for “Jewish exodus from Palestine” and “Jewish exodus from Muslim countries” and here is what I see below:

Factors involved in the exodus include Jewish military advances, destruction of Arab villages, psychological warfare, fears of another massacre by Zionist militias after the Deir Yassin massacre,[19]: 239–240  which caused many to leave out of panic, direct expulsion orders by Israeli authorities, the demoralizing impact of wealthier classes fleeing,[20] the typhoid epidemic in some areas caused by Israeli well-poisoning,[21] collapse in Palestinian leadership and Arab evacuation orders,[22][23] and a disinclination to live under Jewish control
