“I don’t think you (or I) can say what level of gadlus Rabbi Avigdor Miller achieved. It is unwise to simply declare that he was not in the same category as Rav Moshe Feinstein.”
I disagree. I think it is very important to differentiate. I can freely disagree with Rav Avigdor Miller. I can not disagree with Rav Moshe Feinstein. At least not for the most part. The truth is that it is POSSIBLE that there are certain types of things that I would be able to disagree with Rav Moshe Feinstein about, but I would have to be much more careful about thinking that I could disagree with Rav Moshe and it would only be in certain types of areas if at all, and even in those areas, I would have to be very careful.
I think that one of the reasons there is such a lack of appreciation for Daas Torah nowadays is the fact that people don’t distinguish between the Gedolei Hador and Talmidei Chachamim.
