Bradley, you keep coming up with thought-provoking questions like this...maybe we'll have to reschedule your lobotomy.
I think the history of eschatological religions demonstrates that, typically, they survive, albeit in perhaps a highly modified form. The True Believer outlines quite nicely the social dynamic underlying the evolution of such groups.
imo, the WTS is here to stay, and whatever (inevitable) changes occur will be from the "grass-roots" level. The GB will be forced to change policy, as a matter of survival. For example, the decreasing level of enthusiasm for the preaching work, diminished contributions, lack of "enrollment" of the younger ones, the effect of legal actions...these will all lead inexorably (and, to some extent, already have) to a series of changes. Eventually, I suspect, the WTS will become yet just another "socialized religion."
For that reason, I feel that focusing my efforts on individual JWs is the most effective way to "take down" the WTS; and in the meantime, helping people in lieu of attacking an organization gives somewhat more immediate satisfaction...
although it wouldn't bother me one bit if somehow, someway, a "Goliath-killing" lawsuit chopped the WTS off at the knees.
