Oompa, that's why I wish the WTS would make things harder on the friends. That way, some of them might do a cost/benefit analysis and realize that it's not worth it! We know that there are plenty of JWs out there that know that at least some of what the Society teaches is B.S.
Heck, I know one active JW who has told me on numerous occasions that he doesn't believe in God and that the Bible is a bunch of crap (his words, not mine). But folks like that stay in because it's easier than getting out.
But, if the WTS started making it harder to stay in...then you might see some of these "weaker" JWs start questioning whether it's worth it.
That's why I wish they would go back to hour-long public talks, 30 paragraph WT studies, week-long assemblies, etc. In fact, I think they should go back to the old-school Rutherford style of "witnessing" by picketing in front of churches on Sunday mornings with signs that religion is a snare and a racket. How many of today's "country-club" JWs would have the courage to go out and picket in front of their neighbors' churches?
If you want to see an example of what JWs used to be like, check out my old thread here (http://www.jehovahs-witness.com/12/166078/1.ashx). I mean, who knew that Judge Rutherford fought for our right to call cops "god damned fascists"?
