I don't believe this type of treatment is what Paul had in mind. In the book, In Search of Christian Freedom, Brother Franz analyzed this topic from all angles, and what the Society practices is simply not Christianity by any measure.
In regard to the Witnesses, it does probably vary, place to place, individual to individual. It probably matters why one is going back. If we are here, we don't believe it's the truth. And while the association with family and a few friends has something to do with it, I believe some of us want to help awaken them. Or make the attempt, because we well know what we are up against.
Just like the people in Jonestown or Waco, Witnesses are victims of BITE mind control. Some days, I forget that, and I am quite angry. But then, I remember, "That's right, it's a cult! This is what cults do."
