"I have many other anecdotes, but I think part of the problem is the cult mentality that has long been a part of the movement's history. Chabad Chassidim have an elitist attitude and they would be much better off with studying good old fashioned Muusar rather than the obtuse metaphysics of Chabad Haskalah which causes these young students to experience a profound spiritual disconnect with reality.
I have long left the movement, decades before the Rebbe went insane with his Messianic meglomania. In my opinion, Chabad functions exactly like the BORG from Star Trek. Resistence is futil, be prepared to be assimilated.
Whereever Chabad goes, they show zero respect for the religious institutions of the communities they have relocated to. They aim to displace ancient Jewish customs with their own "Chabad" traditions. The movement is sick and I am disgusted with them. Their movement should be branded as "Chabadanity" -- a word that rhymes with "insanity.""
