Something I find ironic is every JW knows the story of the JWs during WW2 and the holocaust but very few know the story about the failed 1975 prediction and how many walked away shortly after. Also how in 1981 they made officially quitting the same as disfellowshipping and how it was connected to the 1975 screw up.
I think it is kind of rich that during WW2 all a JW to do to leave the camps was to sign a piece of paper. Now they have to blackmail them into staying.
