So who is that organisation if it’s not Jehovah’s Witnesses?
IMO, this is the biggest hurdle when trying to open someone's eyes. Most people that i've debated with, although agreeing with the issues i raise, revert back to this question. If they are going to quit the Watchtower society, they want a better alternative - someone who is doing a better job.
Trying to convince someone that they can "do their own thing" is not easy. People are used to having and following rules and regulations. They are used to having a structure and boundaries they feel confortable with. Trying to push this responsability on the individual is not an easy task - in fact many don't want it. They find it easier to follow directions.
I understand it because this was the last hurdle for me as well. I recall conversations with some friends and family about issues within the Watchtower and each time i asked myself "Who else is better?".
It is only when you finalize realize the purpose of a church in not dictating and managing your life, but instead simply providing spiritual support and association, that you come to consider that it's ok to be a part of a group that doesn't necessarily thinks like you.
