Rabbi Hershel Schachter Shows Rudeness Toward the Rambam
Quoting from an article:
The Beis Shmuel (Rema, Shulchan Aruch Even HoEzer siman 90, s’if kattan 6) thinks that even if the Rambam agrees with the Ri Migash on a position not agreed upon by other poskim, this view should be totally ignored, since the Rambam was so taken by the genius of the Ri Migash (his father’s rebbe), and would naturally be inclined to accept his opinion without even thinking twice (even though in several instances the Rambam does reject his opinion), this psak would be considered a shitah y’chida’ah and should be totally ignored.
