Just wanted to welcome you.. The Proclaimers book had a significant part in my leaving as well so I found it interesting you should mention that.
I have not been able to get my family out and that has been disappointing. But with others I have found that living a good life and enjoying it outside of "the lie" and patience to be the most helpful in getting others to leave. Directly tearing down someone's beliefs and being bitter about the past will often have the opposite effect than intended.
