oomis: PM’s comment regarding “anonymous rabbis and family members” was a response to cherrybim, NOT YOU.
cherrybim: We have been cited several times in this thread the chapter of the Igros Moshe supporting PM’s statement. Where is your citations of the Igros Moshe regarding your claims of Reb Moshe ZT’L? PM is certainly correct that you cannot rely on anonymous sources. At minimum you need to cite a verifiable Rav/Posek who will agree with your assertions regarding an unwritten psak of Reb Moshe. Who are these (still anonymous) “talmidim and family members” who are in accordance with your assertions?
