Literally just that: Some dipshit european that went to the Zionist state to get property subsidized by the fascist government and acquired by genocide and land theft.

A settler colonist, someone who is not native to a place who has moved there in a process of actively pushing out, subjugating, or exterminating the actual native population (Palestinians).

An Israeli living in the occupied parts of the West Bank, outside the internationally recognized borders. The West Bank settlements serve as a means of territorial expansion, frequently exist on the best arable land or above fossil water reserves, regularly see violence enacted through the colonizers, and also have seperate courts for Israelis (tried under normal Israeli jurisdiction) and Palestinians (tried under martial law).

The same thing it's always been, a colonizer who steals lands and kills its current occupants
