Below are some excerpts of an excellent fisking. BZ really hits the nail on the head. If you haven't read his blog, you might want to consider it. I'm a big fan.
Just because Carlebach had a bigger beard than Klepper and sang with an Ashkenazi accent doesn’t mean that his music is any more “traditional” or less “modern”.
Rabbi Rudin is falling into the Artscroll trap of identifying “more traditional” with “consonant with contemporary Orthodox practice, regardless of vintage”.
Maybe they’d have more success if they weren’t trying to make it “meaningful to everybody”, and instead tried to pick one thing and do it well. “Led Zeppelin didn’t write songs that everyone liked. They left that to the Bee Gees.”
Ok, so teenagers are looking for outward ways to display their Jewish identities. What’s the problem with that? This list might also include Tzahal T-shirts and chai necklaces. I think it’s harmless; it’s the adults who are turning this into an ideological movement, not the teenagers. The adults should stop projecting their own issues onto the campers and go read Erikson.
