I've always told my friends and family when asked that I didn't have issues with the congregation or elders or anyone, but I did have issues with the corporation. Some get exactly what that means and go no further. Those that wonder what I mean just tell them to google something, usually something specific. I don't send links to anything unless I know it's completely safe. The Candace Conti thing was very effective, especially once they got into the youtubes. The Australian Royal Commission was also very effective. There is so much out there now, if you can drop a hint like "man I never thought this would ever happen" about the cases in Montana/Pennsylvania, Norway. Dave Gracey's experience as an elder and the case with his daughter and the elders and Utah Supreme Court should be eye opening to anybody.
My goal was always to plant a seed, a quick thought of something they would not forget. It could be an inconsistency with one of their doctrines, or hypocrisy with giving "aid," just a thought with a bit of acting thrown in with my own "shock". Maybe when they hear it at the hall or wherever, they will remember what it was I had an issue with.
Good luck!
