it was Jonestown...Jim Jones - the suicides...
I had known they were off track on armageddon, blood, bad translation, memorial two class system, etc. for several years. But when Jonestown happened I did the logical comparisons. They were not just wrong doctrinaires; these were dangerous control freaks who were perfectly willing to have you go to prison, get massacred by hostile crowds or governments, or die from their weird medical superstitions. They also cared nothing about moving you off into a sort of "self imposed jungle of isolation" to be cut off from all society. They believed in God-like society presidents and star chamber committees and would not accept outside viewpoints. THEY (WE) WERE A CULT!
There was a TV interview in Okla City of a young woman who had just got up and left Jonestown a month or so before the koolaid party. The TV lady asked her how she knew to get out...she replied that it all came to hear after Jim Jones had been ranting on during one of his sermons about how sick he was and how the hard he worked to sacrifice himself for his ungrateful people, blah blah...She then saw a TV news program that showed the Oklahoma Sooners had just won the Orange Bowl and were the NCAA champions. She said, I just got so homesick to hear about the team. Then, she said "I got to looking at coach Switzer, and thought about Jim constantly whining. I just thought - you know, your not god, your not Jesus Christ, your not even much of a MAN!"
I know for a fact that this event shocked quite a lot of "good" witnesses; but most just blocked their own senses and kept on drinking the koolaid.
