Gig,
I am certain that they are absolutly aware of the lies and deception they are foisting on the faithful. They are not just some set of equally self-deceived old fools acting in good will. Let me tell you how I came to thise conclusion.
I've been away from the WTS for some time now. When I decided a couple years ago to surf the web for J-dub stuff, I went looking for 1975 in particular. I was amazed at how easily they had sidestepped the issue for the next generation. They simply claimed that they had never foretold 1975, and that it was the fault of the overzealous faithful that took some statements out of context and 'ran with it' as it were. The GB, particularly Freddie Franz, stated that they had never said that Armageddon was going to arrive in 1975 - simple denial.
Well, I continued to surf and found plenty of stuff referring to 1975 in the pre-1975 literature. I found stuff in various sites throughout web - old watchtowers, Governing Body speech transcripts, and books right up to the early 70s. You wanna know something? If you approach the references from a strictly did-they-ever-say-'Armageddon in 1975' view, you will notice how close they get to that statement, but never actually make that statement. The faithful was clearly expected to infer 'Armageddon in 1975', but the GB maintained 'palsuable deniability.'
My point: No way could they have skirted so close to that line, so often, without knowing they were doing it. Bastards.
