I don't want to get involved in all this, but I can't help but say that the way you are talking about R' Schach is wrong. There have been many cases throughout our history where Gedolim argued (cartloads of Rambam's Moreh Nevuchim were burned and as mentioned earlier in this thread R' Yaacov Emden and R Yonasson Aibeshutz) and it was L'shem Shomayim. Obviously you won't agree with R' Schach if you are Chabad, but to say it was Sinas Chinum is wrong. He felt there were serious problems with Chabad and voiced them L'shem Shomayim, not because of Sinas Chinum. ... My point is that each should go according to their mesorah and that G-d has His ways of figuring these things out. Btw none of this is an attack on Chabad, I personally think they do great things (kiruv and otherwise) and I have davened at their minyanim many times and benefited from Chabad houses; I have a lot of Hakoras Ha'tov to Chabad.
+1 Please, everyone, stop calling OTHER PPL"S GEDOLIM names and accusing them of sinas chinum etc. There is a lot to say both ways but that is not going to change anything here. Have any of you ever spoke to Rav Shach?? Ever saw him in person? He had taanos and was and is revered by many many Yidden all aound the world. To say "more than the Rebbe" is irrelevant. I am not going to go into stats now, I do not know them but I do know that many parts of Klal Yisroel held of Rav Shach and did not hold of the Rebbe. Many held of both. Chabad holds of the Rebbe alone. There is no point for us to mix in to their machlokes. We must not castigate either of them.
As my mother likes to say, "If a child is doing something wrong, the parent does not LIKE to hear about it. The mother or father KNOW what their kid is doing but for a third person to come and talk about it is painful. So too, Hashem knows everything about the Rebbe and Rav Shach, much better than we know. Hashem can judge them. For us to talk about them is a disgrace and hurtful to the Shechina"
