R’ Eliezer the Tana held that you can be mchalel Shabbos not only for the Mitzva of Milla but for maksherai Milla as well. His whole town followed his psak and where even saved from a terrible decree for doing so. Can I bring his opinion as evidence in a halachic discussion on the subject? No. Why? Because while EVERYONE held that (1) He was a great Tana and (2) his town was certainly obligated to follow his psak his opinion on this matter was rejected by the rest of the sages of his and subsequent generations. So…
1. In light of the above when answering questions regarding matters where the Lubavitcher Rebbe Z”L took a position that has not been accepted by others it doesn’t make sense to use him as the source for your answer. The refusal to accept such an answer does not = rejecting the Lubavitcher Rebbe as a Gadol B’Yisroel and does not = refusing to accept all legitimate Torah sources.
