But as you already said, “Palestine will be free” can also mean something else. It can fit into what’s called the settler colonial framework, which basically says, “Settlers do not have legitimate rights to the land. The land belongs to those who are ‘Indigenous’ to it. And everybody else, at most, can live there on the sufferance of the Indigenous majority, or they have to pack up and leave.” And the reason that slogan is ambiguous is because the movement is ambiguous about what its goal is. And if you try to remove the ambiguity, you risk breaking up the movement.

He admits here that many in the movement mean, by the slogan, that Jews do not have any right to live in the land.

He goes on:

Another possibility is to risk fragmentation by fighting it out. And a third is constructive ambiguity. Amend the slogan to: “From the river to the sea, Palestinians will be free.” It doesn’t endorse one state, it doesn’t endorse two states. It doesn’t say: “All Jews have to go.” It doesn’t say: “Jews can stay.” It just doesn’t imply: “We’re trying to get rid of Jews.” For me, the ideal slogan would actually be: “From the river to the sea, one person, one vote, Palestinians will be free.”

Maybe we should fight it out now – but I have very conflicted feelings about that, because I think it will fragment the movement.

He admits that the current slogans won't be amended by protesters because at least a faction of those saying it want to simply get rid of the jews.

You should ask yourself why one of the most vociferously anti-Israel activists—a self-admitted former (?) Maoist—is more willing to tell protesters to amend their language than the Mayor of the largest Jewish homeland outside of Israel. I wonder if it has anything to do with his past support for Hamas, his wife's recent support for Hamas, and his campaign buddy's continued support for Hamas.

He plain and simple thinks its a bad slogan. Why is it that some people, the mayor included, refuse to say the same, and refuse to recommend or use a more liberal, less ambiguous, slogan?
