To Yserbius
You’re absolutely right. I don’t understand why such brilliant Rabbis have anything to do with Chabad. If you shake hands with a Lubavicher he takes it as an acceptance of the Rebbe as your savior. Rav Moshe accepted Rabbeinu Tam Tefilin from Chabad. He looked at it as a Mitzvah opportunity. They brag that this constituted Rav Moshe’s acknowledgment of the Rebbe’s superiority.
