In regard to the gedolim quotes, especially since many were compiled after death, I find it hard to believe that they are being interpreted correctly. (Ex: the “MO is like conservative/reform” quote is in Mishnas Aharon, which is a posthumous compilation of different sayings/ hespedim from Rav Aharon zt”l, if I am informed correctly) Especially in light of the fact that is well known that Rav Aharon zt”l and Rav Soloveitchik zt”l had tremendous respect for each other, as evidenced through stories, pictures and writings. They could be hyperbolic rhetoric (ex: statements that kippa Sruga communities are “Amalek” CH”V; or the previous quotes that RZ is “AZ”, which obviously is not meant literally) or based on misinformation. Even if they are interpreted correctly, as stated before, MO is often used as a term for those who simply don’t know or just don’t keep Halacha, and the majority who do and properly deserve the term MO are payed little attention to.
There have been and are BH so many gedolim produced by and in support of the MO viewpoint. Even if you don’t like their hashkafa, are they REALLY kofrim? Do you (or more importantly, the gedolim [not to say you aren’t one! I don’t know]) mean that with all of your heart? It’s a hard road to take. Those who disrespect Rav Soloveitchik, I’m guessing, have never drank from his wellsprings of torah and don’t know/choose to ignore his great impact on all of frum yidishkeit.
This is a pointless argument, in the effect that those biased against MO will most probably not change their opinion for any reason. They don’t have to. But it would be nice for some serious consideration to occur, something which I feel won’t hurt anybody.
