What is your definition of Zionism, OP? I feel like the word "Zionism" is often used pejoratively in the West to describe Jews that prioritize the state of Israel and its influence in the middle east over anything else. I also think Israelite expats (or descendants of Israelites) who are Zionists tend to spread their ethos among their host country while still preferring to still be around their own kind. I do not believe all Jews are Zionists, although I do think Zionism can be conflated with Cronyism. For example, if you were to ask a Zionist who they would prefer for a role with massive political influence, they'd likely favor another Zionist over a (white) gentile. The same could be said about other forms of nationalism too (look at Quebec for example... non-French culture and non-Catholic culture outside of Montreal is heavily frowned upon. Quebecious culture might be pro-white, but it does discriminate against English protestants.
Point being, I think your definition of Zionism likely differs from mine, as I think Zionists will always favor Jewish causes over anything else. Also, if you have anything to corroborate this claim (maybe a website where middle easterns talk about Israel being a "White colonial outpost"), I'd like to see it too (not trying to come across as snide/dismiss your claims as dubious, by the way. I have intentionally distanced myself from the Israel-Palestine conflict because I hear about it ad nauseum across all forms of media, so I'm just genuinely curious/want to educate myself):
