gary, i think u have seen the truth of the problem>.....
in my experience inside the org. most witnesses do not fully understand the supporting reasons for beliefs.
i.e. most witnesses know the witness view of 1914 --- but, ask them to prove, (without a text book) how that date is arrived at, and they will not be able to do that.
during my time there i spoke to many so-called 'opposed' husbands, and found that the basis, for the label 'opposed', was the inability of their wives to explain (and prove) their beliefs.
one poor guy, who i think was genuinely trying to understand what his wife was on about, told me that everytime he asked her to explain something, she would start yelling that he was persecuting her.
it's tough for people without much formal education to understand 'reasoning' processes --- and that, i think, is the biggest failure of the jws. --- they are afraid to teach 'logic' etc because they know that in the process, the 'can of worms' would explode.
so the WTS is content to have a membership with a low level of education, rather than to face the tough rigors of intellectual questioning from it's members.
