jews and arabs together, coexisting. If one views zionism as supporting jewish self determination in the land (which doesn't have to exclude arab self determination, side by side, there were a small minority of pre state zionists, whose goal was a binational state, who still viewed themselves as zionists).

Or in other words, I'd argue that many of the jews (probably not all) involved in this school (I wont speak for the arabs), view what its doing as a requirement for zionism and to rectify failures of zionism in the past, but that they don't view themselves as not zionist. (there are also arabs in Israel who are bigger zionists than some of the jews, one only has to go to druze villages in the Galilee to see this)

But it goes beyond that, this school system has been lauded by the "zionist" state. Yea, there are those in the country who hate "coexistence" schools like it (one can only look at the arson that took place a decade or so ago), but the fact that its actively supported and lauded by the state that you seem to think it rejects. Or in different terms, if one views anyone that supports the continued existence of the state of israel to be a zionist, I don't see how one can't consider this school to be "zionist" (and therefore, anyone supporting it, is supporting a "zionist institution".

Of course, one can also not be willing to say everyone that supports the continued existence of the state of israel to be a zionist, but that doesn't quite fit with you wanting to paint all zionists with the broad brush that you do. In regards to that broad brushing, I'd argue that the palestinians and arabs in general should then be painted with the same brush, because they have done the exact same things and many of their leaders have praised the exact same things. If you're not willing to paint them with the same brush, why are you willing to paint jews/zionists as a while with that brush?

Personally, I'm not willing to paint all palestinians with such a brush, so IMO your broad brush strokes reflects more on the you, than on Israel.

All the above isn't to say that either of these people support what the state of Israel is doing, but many unabashed zionists also criticize the state for its failings. I don't quite get why to some, sins of the state of israel (or zionism in general) are prooftexts to the zionism/israel being illegitimate, but to those same exact people, very similar sins done in the name of palestinian nationalism, don't brand it illegitimate. In practice (from my biased view point, used more in the statistical sense, because of what I've been exposed to, than in the prejudice sense), I see much more self criticism within the zionist movement from its inceptions till modern times that I see within palestinian nationalism (but again, thats because I'm exposed to much more aspects of zionism). And even with that biased belief, I try to deal with respect with any person who believes in palestinian nationalism and deal with them as an individual and not paint them with the broad brush strokes (though, in all honesty, I don't always succeed, as well as realizing that if they can't deal with me an individual and therefore view me as guilty of all the crimes they might place on the state, there's no where to even start a conversation, so its better to just move on, as any argument is just going to create confirmation bias (in this case more related to prejudice) in me going forward impacting how I relate to others.
