Well, I have to hand it to them. In at least one segment of their operation, their university branch, they owned up. Their pretenses are gone. They were not pro-Israel at all, and they were dropping "pro-Israel" from their nomenclature entirely. In fact, it is now dropped and they are frantically trying to explain themselves to their fans.
One of their spokesmen said that they had basically to follow their followers. On their campuses, the split-offs from the split-offs will not tolerate the reality of Israel as the sine qua non of peace. OK. See how they fare. I know that there are, here and there, fistfuls of hold-outs against what probably is the greatest revolution of the twentieth century, the Zionist revolution, which transformed an entire people and built a commonwealth that is in a league with any in the West. Part of the Jewish revolution was the struggle against these recalcitrants, the most pathetic of whom were the German Marxists of the 30s, arguing with the Zionists who were trying to make a real life and not live by fatuous ideas.
But at least Walter Benjamin was a genius. J Street's philosophers are Spencer Ackerman, Matthew Yglesias and Philip Weiss. You can sample this kind of thinking on the web sites jews sans frontieres and other anti-Zionist blogs.
