When you say This would seem to dispel the idea that a religious influence stays with a person into adulthood I'm not sure your findings are entirely accurate, Jock. I don't believe atheists are simply 'put off' by having religion in their background. They are far more likely to have deliberated upon the lessons of childhood, searched for any evidence of truth and rationality within those lessons, and by a process of logical thought, reached their final conclusion. In order to ascertain whether or not religious influence stays with a person into adulthood, and to achieve a more balanced result, you would need to carry out a survey of believers to establish how many of them were exposed to religion in childhood.
