My God.....this is awful, just AWFUL treatment of volunteers (no less, treated like slaves).
The only other thing I've heard of that even comes close to this level of cold, callous, evil treatment is what members of Scientology receive at their own "Big Blue House."
And to think, this was back in the 1970's, and this type of cruelty is still alive in well at WT HQ, and will be just as alive in the new WT HQ being built. These leaders are sick in the head, "mentally diseased" to the core. Totally whack.
