For the first 41 days of 1975, I was in the womb (I guess this makes me a little older than you, PLH! ) My parents converted in 1977, so I managed to squeeze in two birthdays before my life was cast in the grim shadow of Jehover's Organization.
I did, from time to time, hear about the 1975 mess, but it was always said that certain unfaithful ones started false rumors and eventually left because of teachings that did not originate from the Faithful Slave (tm).
So, I was under the impression that a small sect or cult of crazy people broke off from the larger sect or cult to which I belonged. They were rebellious, independent-minded, and most of all, really really stupid for believing the end would come in '75, especially when the Organization never said it would!
Imagine my surprise last summer when I finally researched the stuff for myself.
