how is that not colonization?

I'm going to assume good faith here and that you've just never actually bothered to read a book but it's really really hard not to insult you for this shit. Colonisation is what happened to Palestine. Colonisation is settling a land, often owned by someone else, and stealing it from them, usually while engaging in ethnic cleansing.

If this is not what you mean then you need to stop calling it this because it's complete and utter bullshit.
