Ethnic cleansing is the systematic forced removal of ethnic, racial, or religious groups from a given area, with the intent of making the society ethnically homogeneous. Along with direct removal such as deportation or population transfer, it also includes indirect methods aimed at forced migration by coercing the victim group to flee and preventing its return, such as murder, rape, and property destruction.

Forced expulsion of Palestinians has been central to Zionism since the 1880's

There are a lot of factors of the Jewish exodus from the Muslim world, but your conflating of the two as justification or minimization of the Nakba doesn't work; unless you somehow think all Arabs or Muslims are the same. But it's pretty clear your racist towards Palestinians or Arabs or Muslims when your argument boils down to 'they are violent primitives and deserve to die,' just going straight to dehumanization and ignoring all material conditions of Apartheid

Iraqi-born Israeli historian Avi Shlaim, speaking of the wave of Iraqi Jewish migration to Israel, concludes that, even though Iraqi Jews were "victims of the Israeli-Arab conflict", Iraqi Jews aren't refugees, saying "nobody expelled us from Iraq, nobody told us that we were unwanted." He restated that case in a review of Martin Gilbert's book, In Ishmael's House.

Yehuda Shenhav has criticized the analogy between Jewish emigration from Arab countries and the Palestinian exodus. He also says "The unfounded, immoral analogy between Palestinian refugees and Mizrahi immigrants needlessly embroils members of these two groups in a dispute, degrades the dignity of many Mizrahi Jews, and harms prospects for genuine Jewish-Arab reconciliation." He has stated that "the campaign's proponents hope their efforts will prevent conferral of what is called a 'right of return' on Palestinians, and reduce the size of the compensation Israel is liable to be asked to pay in exchange for Palestinian property appropriated by the state guardian of 'lost' assets."

Israeli historian Yehoshua Porath has rejected the comparison, arguing that while there is a superficial similarity, the ideological and historical significance of the two population movements are entirely different. Porath points out that the immigration of Jews from Arab countries to Israel, expelled or not, was the "fulfilment of a national dream". He also argues that the achievement of this Zionist goal was only made possible through the endeavors of the Jewish Agency's agents, teachers, and instructors working in various Arab countries since the 1930s. Porath contrasts this with the Palestinian Arabs' flight of 1948 as completely different. He describes the outcome of the Palestinian's flight as an "unwanted national calamity" that was accompanied by "unending personal tragedies". The result was "the collapse of the Palestinian community, the fragmentation of a people, and the loss of a country that had in the past been mostly Arabic-speaking and Islamic.
