I think Pale Emperor may be on to something. My last association with a congregation (1998-2003) was an eye-opening experience where I began to see TTATT even before I knew what it was. The numbers of young wives leaving their husbands was unbelievable. Nearly all went to the World. I now have a better understanding why.
While it is true that many leave the Cult in a state of high morality, it seemed to me that most left the Cult during my association for reasons of "immorality." Can't really blame them...
