The goal here is social justice for Palestinians, as of now, they don’t have civil rights, political recognition, nor any non-violent avenues of resistance. So I get your sense that, yes, these are urgent issues which needs addressed. But the anti-Zionist will not stop until full justice is achieved. Maybe you are looking at an anti-racist while slavery is still a thing, or a land-back activist during the trial of tears. Perhaps you are a reformist being presented with a radical (i.e. looking at the root of the issue) solution.
For me the root of the issue is the settler colonial prospect of Israel, while Israel wants to maintain any ethnocratic policies (i.e. zionism) it will have to come at the cost of civil rights for Palestinians. My solution is to not grant Israel the right of ethnocratic policies.
I think the only thing I'd put on the table here past just recognizing that we're working from incompatible premises (at least, when we get past a Palestinian state and self-determination, and probably Netanyahu in a prison cell somewhere) is to try to stay cognizant of whether the standards you're setting for Israel are the same as those of other countries or other people or other ethnicities or whatever. because there's a whole grim history of people pretty much everywhere in the world singling Jewish people out as moral "others". But if you're being consistent about stuff, I don't have much to push back on.
I understand and can take seriously a narrower "anti-Zionist" definition that pushes back on "Greater Israel" ideology that impedes Palestinian self-determination.
But what we're talking about here is basically: "I reject the premise of the state of Israel". To which, and I mean this respectfully, the only reasonable response I can see is "it's good to want things, I guess".
(It's fine if we just intractably disagree; it would be weird if any two people here never did.)
