Well Gary, here is a subject which we can completely agree on.
I remember the thoughts that went through my mind when a brother who had begun to have serious doubts started speaking to me about them. At the time I was a book study conductor and he was assigned to my group. As soon as I realized where he was leading the conversation, it was as if alarm bells were going off in my head ***APOSTASY ALERT--APOSTASY ALERT***. He brought it up again a couple of times while we were out in field service together and all I could think of was, 'Gee, poor brother so-and-so needs some help, he's really going off the deep end.'
Having this experience in mind, when I left I didn't bother trying to convince my family or acquaintances that their faith was misguided. I knew it would be a complete waste of time and only alienate them. When they're ready--they'll see it. In the meantime, I think the best thing that ex-JWs can do is to get on with their lives and not obsess over the past. Seeing members who left the group leading happy productive lives is the best "witness" you can give to your JW friends and relatives.
