Good post. I believe it's true that people want their illusions. I have an interest in modern urban legends, the stories people tell that happened to "a friend of a friend". I sometimes get them in email from, and I am often astounded that people forward these things with out checking to be sure they are true. Often the story has a payoff for them, it either validates a belief or reinforces a moral they hold dear.
For example, there is a MUL that "In God we Trust" was taken off of the dollar coin, they even had a picture of the coin missing the term. The idea was that this was a plot by atheists to take away any mention of God by the government. People were urged to refuse to accept these coins and to contact their congressman. The only problem is that the term was not removed, but simply put on the edge of the coin temporarily, by the time of the email The term had already gone back to the front of the coin.
Instead of being happy that there really wasn't a plot to remove religious terms from coins, the sender was quite peeved that I had pointed this out. They wanted to believe in a plot by atheists, as it validated their world view, they probably assumed I was the one making things up. It's very hard to counteract this kind of thinking, people believe what they want to believe, God forbid you confuse them with facts.
