Zev, that was a thoughtful, well research and commented post. You really know how to do your homework, and I hope that newbies, lurkers, JW studies, and even a few JWs who have open minds will allow the simple truths in it to seep into their consciousness.
In your post, quoting the JWs, was this phrase, which was to characterized young people selected to testify, "...clean, moral, honest, but..." That BUT pretty much says it all, doesn't it? It's the point at which the society switches from saying the truth be told, to the point at which the society says the truth must be shaded, diluted, and TWISTED.
And I would also add that while, yes, the issue is one of double standards, I'd also say that it also goes far beyond that...it goes all the way to the basic honesty of the WTB&TS, which - as we can see from your post - is utterly lacking. The real issue here is the organization of Jehovah's Witnesses subornation of perjury, LYING UNDER OATH.
I can recall no instance of Jesus, in all his dealings with the Pharisees, Saducees, scribes, governors, and kings, ever taking a lawyerly approach to their attempts at trapping him. Never. He spoke the truth with out fear or favor; he spoke it with no hint of even the slightest turning of a hair to deceive; he spoke it honestly and plainly in simple language the could be understood by all.
God, how I despise those lying bastards at the WTB&TS and their myrmidons.
