Mungo,
It may not have been true in YOUR case but it does happen. I personally finally sent my DA letter when they came after me for having a worldly gf. Since I knew I was headed for the big DF I took charge and told them how I really felt about their teachings, manmade publishing corporation inconsistant "New Light" and a host of other things. So while I formerly DA'd they made it clear that my dating a worldly girl was going to earn me a big fat DF on my publisher card.
