Yankel Berel had two posts which I found interesting. The first was about the appellation Nosi Hador, which, YB argued, is a new and non-existent title that Lubavich uses to show that their rebbe was/is above all others. I have argued at lenght the exact same thing in the past on another thread in the Coffee Room.
It is very much in line with their ludicrous statement – again, I’ve heard this one many times – that when other chassidim say stam “the Rebbe” the mean the Lubavicher rebbe unless they specify a different title.
The second post which I find interesting is his explanation how Lubavich managed to get so far off the track by “testing the waters”. I don’t know if he’s right, but it is certainly worth looking into.
