Avi K, I strongly protest your last paragraph above. It is hateful and very offensive.
Up to that point, though you did make a good point. When Chasidus started off, there was huge opposition among Rabbonim. There was the famous cherem. I don’t know about that particular story, though it is vaguely familiar. I would recommend the Artscroll biography on the Vilna Gaon which delves into that painful period for klal yisroel.
