I recently had a discussion with my JW sister who I know has her share of doubts. She can't get past the blind faith reasoning. She and her Elder husband have been crapped on so many time by the goody two shoes type JW's but always say it's people not Jehovah who are imperfect. They really don't want to dicuss anything because it brings up too many questions they can't answer.
I don't push it as they are pretty laid back. Both my older sister and I are DF'd and they still talk with us and we stay at each others places when in town. They are 2 of the best people there are but won't question a thing about the org. It frustrates me to no end but I just try to be calm and reason with them.
