With a second question on whether he would write it differently now:
One of Beinart’s key goals is to question the narrow parameters that communal leaders attempt to impose, with some success, on American Jewish discussion of Israel. The trouble is, those narrow parameters also preclude questioning the narrow parameters. Pushback was inevitable.
But that doesn’t explain the attacks’ venomous, ad hominem intensity. For that we must look to the general mood of panicked rage sweeping some segments of Israeli and American Jewry: the McCarthyite attacks in Israel on human rights organizations and the New Israel Fund, the attempts to keep J-Street speakers out of synagogues and to defund or shut down Israeli film festivals screening the wrong Israeli films. The legal threats against campus Arab student groups. The hounding of M.J. Rosenberg. It’s hard to remember such a dark mood of repression since the days of the enemies’ lists circulating in the community in the early 1980s.
