First of all, the Society has never been good at taking responsibility for their false prophecies expectations.
I was 20 in 1973 when I was baptised after having studied several books with girls I met at school. They had convinced me that the big A would be coming in 1975 by showing me "the signs of the last days" alongside the made-up WT chronology. I married in 1974 primarily to have someone to go through Armegeddon with. When 1975 came and went unevenfully the spin doctors and aplogists of the congregation went to work. "We know the season but not the day and hour." "Although Six thousand years of mankind's existence ended in 1975, we do not know how long Adam was alone before Eve was created." "We don't know Jehovah's timetable." etc., etc. Speculation pushed the date of the worldwide destruction back for at least 20 years. Within those next 20 years we had two boys, hubby had become a MS, then elder, I pioneered; in other words we had become deeply entrenched in WT world. We were so entangled that even if we had realized we had been duped it would have been extremely difficult to extricate ourselves from the organization.
As Smiddy says the 60's were a tumultous time with the threat of nuclear annihilation looming. It is easy to see how the WT grabbed hold of this opportunity to promote Armageddon. They just capitalized on the fear of the times to promote their own agenda. Now they have to settle by saying Armageddon is coming "soon", whatever that means.
Of course we finally did extricate ourselves from the organization. It took a move to a totally dysfunctional congregation, a newspaper article, the internet, along with our own nagging doubts to finally wake us up.
