This has been a problem on its way for 30+ years. The late 60s/early 70s numerical growth was fueled by young people who wanted something different than what their parents' churches had to offer. As cultish as we now know TWI has always been, for us young people back then, TWI, at least upon our initial exposure, was exciting. For the children of the first few waves of PFAL grads, TWI was their parents' church and was anything but exciting. Besides, by the 90s there was an evangelical or "full Bible" church on every street corner that claimed to deliver the same "accuracy of The Word" that TWI did...there was plenty of choice, it wasn't just TWI vs. mainstream Christianity any more.
