Whether you are a refugee or not, the act of displacing the native population (and Jews from eastern Europe and Russia are not native to Palestine), and maintaining that displacement and subsequent subjugation is colonialism. In fact, organisations like the Jewish Colonisation Fund existed for the purpose of facilitating immigration to Palestine.
> Jews that moved to Ottoman Palestine, btw, were buying land from locals. Are you saying that buying land is an act of colonialism if jews are doing that?
> Why are you twisting the facts to fit your narrative?
If this is how you characterise the birth of Israel, then you are sorely misinformed. Israel was created through a terrorist campaign of ethnic cleansing starting in early 1948 with the forced depopulation hundreds of thousands of native Palestinians from their villages accompanied by massacres like Deir Yassin, i.e. the Nakba. This was the culmination of the Zionist rhetoric of "transfer" of Palestinians from their land and in effect has continued to this day.
Zionism is a replication of white European colonialism, but performed by Jewish European people, and partly encouraged by European powers primarily for geopolitical and also partly religious purposes (see Christian Zionism). It uses the dubious Jewish ancestral claim to the land as well as past oppression to create a Jewish ethno state and oppress a people who is probably more related in ancestry to the original Jewish people than most Jews (except those that had been there for generations).
