ExB: All this confusion about the where the 1914 thing started is going to be good for the Borg when they try to get away from it.
The thing is, they had pushed it aside. After the 1995 change where they stopped emphasizing the 1914 generation teaching, they appeared to have let it go. I think that they must have felt that not having a way to keep the time pressure on was hurting them, so they went with the overlapping generations teaching in 2010.
So, for 15 years they were letting the 1914 generation teaching fade into the background. Had they let that happen, it wouldn't be such an albatross for them now. Instead, they went with overlapping generations, which is the kind of idea that is so blatantly self-serving that I am surprised more JWs didn't walk away.
