Having read both of Franz's books, more than once, I owe a lot to him for giving a structure to my discomfort with the religion I was raised in. Even if his motives were not pristine, he has my gratitude.
If he and Dunlop had been successful, the WT might be very different than it is now, maybe even tolerable.
The Worldwide Church of God did an about face some years ago, so it is possible such a change could happen in the WT, but I won't hold my breath.
