"In my opinion a Bethelite cannot bring extraordinary proof otherwise he will be discovered by Bethel's spies and executioners."
No-one is asking any Bethelites to out themselves. Elapsed time will be proof enough, should the predicted changes occur.
A lot of the areas in which the WT is only now taking baby steps were hot topics and "imminent" changes 20 years ago.
In the late 90s I offered a $10 bet to a JW that the blood policy would be dropped in five years. He should have taken that bet. 🙄
