Dear Qwerty,
I don’t understand the question. The Rebbe knew shas and knew how to learn. It is a contradiction. All of the Ramabam’s seven causes for contradiction can be applied here. And anyways, this is not even his chiddish. Rav Tzadok Hakohen has a long essay saying that we don’t follow this whole sugyah. And every Jew will be redeemed as well as having a share in the world to come.
Here is a better question. I have pointed out that there isn’t any reason for outsiders to be attacking the authenticity of Chabad. Why have you not defended yourself?
