Dear Qwerty,
That is more like it. But the honest hardcore truth is that you will find Yidden in every group that belittle great gedolim all the time. Chabad just doesn’t realize that it isn’t smart optics. They don’t care about how it looks to others. They are the same in public and in private. Actually, they are better behaved in private. That beats other groups that will talk about how great everyone else is, and then stab them in the back at the first politically opportunity. The Rebbe did not belittle his contemporaries.
