In view of some of the recent comments, I'm going to expose a certain stereotype for the purpose of discussion. It's a prominent and identifiable one, but what I'm about to share does not apply universally to everyone, so bear with me. I've noticed that this game has been played wherever our former religious experiences have been discussed. It starts with:
"Hi, I'm an atheist, and I'm just so intelligent! Let me acquaint you with the only logical method of determining valid information, and the only rational and acceptable way of interpreting it, and then you'll become an atheist, too, unless of course you are just plain stupid!"
Why don't more believers take this bait, and cross over? The fact is, people make benefit assessments in their lives, related to purchases, friendships, relationships, career choice, and even their faith. For some, faith provides benefits which non-belief simply cannot replace. In fact, it often acts as an all purpose solution, or a one-stop shopping center for a wide collection of needs and desirables, especially if one is raising a family. How can an evangelizing atheist replace these tangibles and intangibles with something of greater or equal value? He can't. All he has to offer is a vacuum. Nothingness. It's like a eunuch going to a dance club to try to pick up women.
Back when I built and rode Triumphs, there were always Harley guys who acted as if they were bigger and badder, had bigger dicks, and were more authentic bikers, just because they rode HD.
One of the lessons from life's school of hard knocks is that, no matter our talents, there is generally someone else who has greater talent. Name the criteria. If you start a contest, sometimes you're going to win and sometimes you're going to lose. What you have is what you have, and successful people learn to use what they have effectively. There will always be someone with a higher IQ, more wealth, bigger muscles, hotter cars or bikes, more lovers, better fighting skills, or more persuasive and magnetic personality. What is true is that often people will become jealous and resent formidably strong or obviously superior types. Idolization and imitation are not universal reactions by any means.
The WCG was a seeker group. The ministry was dedicated to attracting people who either had not thought much about belief, or were looking for solutions to some of life's more vexing problems. The church would seek and pick up whatever stragglers they could find, usually by pretending to provide special information which nobody else had, and to use this information to intellectually back prospectives into a corner, leaving them no other logical course but to join up. No matter that the vast majority of the people who heard the message simply tuned it out as being ridiculous. Many ex-members still have retained this methodology, and since it worked at one time on them, they use it in attempting to spread their new ideas, often with missionary zeal.
I'll concede the fact that many non-believers are indeed happier and better adjusted than those like ourselves who have had or are having a bad religious experience. However, for the most part, Christians have some pretty awesome coping skills, and quite a sense of community. Generally, they help one another, and humanity at large, sharing many of their talents and resources. And, yes you can find these qualities and sense of community elsewhere, if you know where to look. It's just that they seem to be concentrated in the Christian community. In terms of intelligence, interests, and abilities, believers mirror society at large, making it easy for anyone to find and form friendships. Friendship is also a very powerful motivating factor in keeping people attached to any collective group. It's one of the major adjustment problems many of the people who left WCG have cited in their lives.
Benefit assessment is the reason why happy believers do not succumb to the charms and persuasive powers of the "Elvis of Atheism" types. Just in case anyone happened to be wondering.
