Why imply that it's a prison for Palestinians? If the Israelis and Palestinians came to a peace deal tomorrow, there would surely be a border. Why is one side of the border considered "a prison"? It's asinine, and typical of the disatisfaction of the left and the Arabists. Nothing is ever good enough for them.
The comparison between the "whites" and the "blacks" is also asinine and incredibly insulting not only to whites and blacks, but to themselves (brown?). They can make what they can make of their semi-state. So far they have chosen to make nothing of it, except to fight for that nothingness. If they think they are "the blacks" (whatever that means), then it's their own damn fault for following a regime of terror and incitement and doing next to nothing to improve their lot in life.
