That Lubavitchers consider the Rebbe their Gadol - I get it and respect it.
But they say that he is the ALL of our Gadol is difficult to digest. Why are other communities choices of Gadol negated?
I recently saw an interesting interview with a Lubavticher Mesivta Menahel who grew up Litvish-Torah Vodaas-Brisk. He said that what Lubavtich and Brisk have in common is that both groups feel that the ONLY way is THEIR way. Everybody else is living a בדיעבד mistake.
