I haven’t replied on the Copts in Egypt and Christians in Lebanon because I don’t know enough. I used to have a friend who was a Copt, back in the 90’s, living in the US. He hated the Muslim fundamentalists. The Arab Spring in Egypt didn’t turn out well. I can’t say much beyond that. I know even less about current day Lebanon. But I understand your concern that an attempt at a fair and just 1ss might disintegrate into something ugly. In a way it already has, since what we have now is essentially a very ugly 1 ss.
Personally, Yonah, I think well- intentioned Zionists like yourself should be talking to Palestinians about their oppression and the solution to it all. Currently you should be working towards ending Palestinian oppression. I am now using “ you” in a general sense, not saying you in particular. ( I’ve never quite understood your situation— do you live in Israel or the US or both? No need to answer. Not really my business.)
There was this writer David Shulman who wrote some pieces at the New York Review of Books. Haven’t seen him lately. My impression is that he was a very liberal Zionist, maybe with one foot out the door. Anyway, he seemed to spend time going to demonstrations alongside Palestinians, trying to prevent demolition of homes and expulsions. Not saying you should be doing that exact thing, but it seems to me that if Israeli Jews want the best chance of a happy ending for everyone, they should be working side by side with Palestinians fighting for their rights.
Beyond that I have nothing.
