A little on a tangent, but relating to your comment about them having to put you into a category - I recently watched a TED talk (Kathryn Schulz: On being wrong) when the speaker talked about the assumptions we make about people who disagree with us. It's easy to see people go through these phases, and I think it's happening with your elders. The three assumptions you make, in order are:
Ignorance (i.e. the other person just doesn't have all the information - Lets read these scriptures)
Then once they realize that you're familiar with all the information/scriptures/WT articles on the topic that they are, they move to:
Idiocy - You just don't understand, you don't have the ability to reason clearly.
Once you demonstrate that you're thinking clearly, they move on to the final one:
The Evil assumption. This is where you're likely at now. You've demonstrated that you have all the information and you're thinking clearly, so the only (in their minds) logical way that you could still be sayings something contrary to their beliefs is if you know the truth, but you're concealing it.
This is a pretty fundamental part of human nature, and I think one of the reasons cults are so successful at controlling people. It's your first reaction to classify intelligent, well informed dissenters as evil. If you have your cult friends backing you up on this assumption, it becomes unshakable.
I don't have anything to add specific to your situation, as I've never been through it, but I want to thank you for continuing to share your story, as it helps me to prepare myself for the road ahead. We're all pulling for ya, and I hope you're able to get out clean.
