Moshe,
I've seen this concept bandied about in this forum before. I'd thought of it myself. I believe the fact that the WTS does not provide for such an annulment is one way they demonstrate a strong degree of disingenuousness. (Disingenuosity?)
Would anyone expect any sort of legal contract to be binding if the one signing it were twelve years old? Likewise, would anyone expect a twelve-year-old to understand the gravity of agreeing to a JW baptism? Of course not. But what is the position taken by the WTS on this matter?
They don't care. Is this because they care much more about their own authority--and the preservation of their religion--more than the many individuals whose lives may be ruined by their enforced shunning? Yes. But it's also because they want to silence anyone who leaves the fold--so that existing JWs do not hear what they have to say.
I consider this a strategy of tight-fisted desperation. It is not one that springs from a confidence that Jehovah is truly directing their organization. It instead springs from fear. Fear that others will discover what departed ones know. Fear that these ones will also leave. Fear that their ecclesiastical power will be diminished. Fear that maybe these departing ones are actually right.
