For those of us who lived through from the sixties until after 1975 we know that not mere hints were given -
In one year leading up to 1975 Circuit Oversser had a special Saturday evening mtg with just cong members (from an outline) to go through the chronology.
No one in the audience was given achoice - this was "received truth" "absoutley correct" "undisputable" - sadly we swallowed that crap
Many I know personally made great sacrifices of themselves and family and they have suffered as a consequence. ANy apologist for the WT and 1975 is either clinically mad, a liar, or deceived beyond hope of reclaim. Those who lived through the period know of the fervour etc whipped up - we did not invent this ourselves or become over excited.
