See my forthcoming, very cranky, work-in-progress poem / essay: "I Am [Not] a Zionist (and [so / neither] Are You)" Who benefits from these arguments? Fascists and crooks.
Which is all a long-winded way of saying: These debates about Zionism and anti-Zionism are mostly unhelpful right now, and I wish everyone could just drop these terms unless speaking historically and talk about their political vision for the future in other terms.
