Nome – i think if your entire judaism hinged on such things you too would be insecure enough to lash out at anyone, even an anonymous name online, who questions it.
Ever see a lubavitcher who first finds out that many gedolim didn’t hold of the rebbe? It gives them a crisis of faith and many go off the derech because of it.
On the flipside, the adulation goes so far that i heard from kne6 lubavitcher that they’re still frum because if the rebbe held of yiddishkeit, it must be the right religion.
