You can drop the term "colony", or "colonizer" et cetera. At this point the term means nothing more than "person who deserves to be displaced owing to his ethnicity and present ___location."
Modern Israel is absolutely a colonizer state. At around the same time that Western empires were dissolving, mostly Western mostly white settlers colonised a piece of the Middle-East by force. I know the situation is complicated, but this is an accurate description, from a dispassionate point of view.
There you go. Rationalizing an intent to subject people to ethnic based displacement. (People who at this point are of mixed descent of every Jewish community, including those displaced INTO Israel from the Arab world)
