Nishtdayngesheft, I hope that that op-ed was just a fit of pique due to his flap with the Chief Rabbinate and that he since has regretted it. While we both have since moved on, when I knew him thirty years ago he had strong criticisms of Conservative and Reform. I also had the impression that early on he decided to play the “good cop” in order to attract BTs and keep marginal FFBs from going completely OTD. In fact, he once commented that meany of those who started in HIR would no longer daven there – and he did not seem upset about it.
However, I do think that the criticism should continue. Hopefully it will do for OO what the Mitnagdim did for the Chassidim (“Mekor Baruch” in the name of the Tzemach Tzedek).
