Yes, this is a Buzzfeed article I stumbled upon, but certainly relevant. Ali Abunimah and Hussein Ibish were once friends, and both have the goal of a Palestinian state. However, the more radical Abunimah and more moderate Ibish cannot agree on how to do so, sparking a harsh back and forth on Twitter. This is not just a Twitter fight, these are two well-regarded intellectuals who are on the same side, but have radical differences. Ibish is fine with a one-state solution and recognition for Palestinians, where Abunimah stands firm that Palestine should not be under control of Israel. These two are a microcosm for either sides of the debate: most want the same thing, but cannot find middle ground, creating a more difficult environment.
