I've often been chagrined by the ample discourse on the supposed suppression of anti-Israel discourse. It's amazing how much press time--and how many book sales--critics of Israel can get while they're complaining about how they aren't allowed to speak or publish or express themselves. It's infuriating.
So, as David Harris notes, it is indeed worth watching and thinking about what happens when the shoe is on the other foot. Somehow, I suspect certain voices otherwise prone to crying "censorship!" will be conspicuously silent. And anyone who speaks up in favor of disseminating a pro-Israel message will be accused of being a "rightist," a "neocon," or some other pejorative sobriquet.
