I'm sure that children who learn there is no Santa Claus or tooth fairy go through some trauma too. They seem to be able to adjust quickly to reality though.
Unfortunately, many of us were so sure we had all the answers for 30, 40, 50 years or more before reality shattered our perception. I guess I can only say, I'm glad I'm not in my 60's still waiting for Santa Claus.
Who knows what will shape my thinking in the future, but I doubt very seriously it will involve a cult or any absolute black and white thinking process. For that I am grateful.
