An object lesson.

John Quiggin "The discussions here and elsewhere on agnotology/epistemic closure have established the existence of a set of mechanisms on the right for propagating ignorance and protecting it against factual refutation. These mechanisms have some obvious benefits, particularly in mobilising resistance against policy innovations, and tribal solidarity against outsiders of all kinds." 

John Mearsheimer "The story I will tell is straightforward. Contrary to the wishes of the Obama administration and most Americans – to include many American Jews – Israel is not going to allow the Palestinians to have a viable state of their own in Gaza and the West Bank. Regrettably, the two-state solution is now a fantasy. Instead, those territories will be incorporated into a “Greater Israel,” which will be an apartheid state bearing a marked resemblance to white-ruled South Africa. Nevertheless, a Jewish apartheid state is not politically viable over the long term. In the end, it will become a democratic bi-national state, whose politics will be dominated by its Palestinian citizens. In other words, it will cease being a Jewish state, which will mean the end of the Zionist dream."

Not a new point but becoming more popular because over time more obviously true. The two-state solution was always a racist one—liberal ethnic separatism is still an oxymoron—but it might have worked. You'll never understand how reason slips into unreason unless you can imagine yourself slipping. Quiggin's arrogance is laughable, more than that it's obscene: blithe superiority is a form of moral passivity. He's not thinking he's assuming, and since this was pointed out to him, politely at first, he's now lying, to himself and then everyone else.
