Agree with notion that -
The fewer elder interactions you have, the BETTER!
Also, I know it's hard, but do your best to limit criticism of the religion when you talk to your parents. None of what you say will matter in their devotion, but it can serve to further degrade your relationship with them to an unnecessary extent. In other words, you can only HURT things, you can't help.
Anything anyone wants to know about the WT is freely available for thorough examination. If people don't know, it is because they don't want to know. There's no lack of opportunity now to learn about such things.
I am hoping that the elders might be done with you - but I doubt it. They may still try...with your parents' help...to maneuver you into a situation where you say/do the wrong thing and thereby have justification to dispose of you via Judicial Committee. This is where you MUST have discretion. Your best protection is your silence. Don't throw it away in an attempt to make some point that will NEVER do you any good.
Good luck...and keep us updated.
