No, Cannedgranny, the reason that religionists so often drop out is that they suddenly come across a language which they are not trained in, its components being evidence, logic, argument, reason and commonsense. It puts them off because they're used to a world of comforting mantras, traditions and dogmas among those of a similar ilk. The challenge is too much for them.
Many times on this site I have asked what it is that believers will be saved from where I most certainly won't. What is to be my fate? Some are too embarrassed to talk of everlasting fires in this day and age (or realise just how cruel that would make their God). Whatever the reason, I have never had an answer.
