Zionism isn't Israeli-Nationalism though, it's Nationalism in the sense of the early Progressive concept of Nationalism. Zionism pushes the establishment of a Leftist secular jewish state advocating Leftwing policies.

It's the same trick that the Left always pulls. Claiming ownership of a block of people and attempting to balkanize them into a body politic for the cause of Socialism. As with Feminism not speaking for women, and Black Lives Mater not speaking for Blacks, and Pan Arabism not actually speaking for the interests of Arabs, and Pan Africanism not actually speaking for the interests of Africans, and Trade Unionists not actually speaking for workers, and Labor Parties not speaking for laborers, Zionism also doesn't actually speak for jews because it is Leftist.

I don't disagree with anything you said, it's just that Zionism itself is another -ism skinsuit.
