A Note On Hatred.
We have long noted how Lubavitchers often respond to even the mildest and most balanced criticism with the charge of sinas chinum. This is true no matter how objective or even friendly is the tone of any letter or book on the subject. This is also true regardless of the lack of any evidence of actual bad feeling. It has unfortunately become utterly predictable that the principle reactions to any suggestion that there might be some problems in Chabad ideology or practice consist of deeply emotional (and often incoherent) accusations of personal hatred and venom.
This is a real shame because it makes it virtually impossible for anyone to engage in intelligent and productive dialogue on the issues that really matter.
