I hadn’t heard of this before. He used to be an Aish campus Rabbi at Columbia, apparently. That’s scary for a couple of reasons:
1. Either Aish is doing a terrible job of vetting for letting this guy in. He could have destroyed hundreds of kids, misleading them in what right and wrong are.
2. Or, it could mean he was actually frum, and living around a liberal, college environment destroyed him. How often might this be happening?
