You never know what might be going on in someone's head.
Exactly right. Shortly after I left, I found myself in forums (not this one) and usenet groups fiercely defending JW beliefs, even though I had no real reason to. I had some difficulty letting go of the notion that anyone who disagrees with the WTS is evil and ignorant, because this attitude was all I had ever known. Looking back, I don't think I really wanted to convert anyone, I just wanted answers to questions that had been bothering me for a long time.
