One of the differences between the Nevi’ei Haba’al and the Nevi’ei Emet, was the the real nevi’im were harsh towards klal yisrael, whereas the nevi’ei haba’al only complimented the yehudim.
Habad is always and invariable complimentary towards am yisrael. According to them It’s never the yehudims fault.
As opposed to their opponents- the litvishe and satmar.
That explains much of the difference between mainstream yehudim and habad when it comes to the sensitive topic of the shoa.
