A crutch is only a crutch if you fall over when it is suddenly taken away from you.
With regard to gullibility, consider that, as soon as an infant is old enough to pose the question "where does the world come from?" to a parent, the answer they are given will depend entirely on whether the parent wants them to grow up sharing their faith (if applicable) or wants to steer them clear of the whole area.
The child probably could not care less about whether the answer is 'the truth', their task in life is merely to fit in and become like the people in their immediate surroundings. They copy behaviours, they listen and repeat, they ask questions when they don't understand something and they accept what they are told without questioning their principal advisors. One is taught not challenge one's parents and one will later be instructed to not question their pastor either.
Unquestioning acceptance of information passed to you is the very definition of gullibility.
The really sad thing is that life was (still is) tough and when children realised that their parents are not all-powerful and can't stop bad things happening, they do become insecure and need some kind of reassurance that things will be okay - if not in this life then 'in the next'.
The 'emotional crutch' is therefore installed at a very early age, for some. :-(
Maybe those of us with privileged, financially secure lives, supported by attentive parents who do have the power to fix our material, financial and emotional needs just don't need the big guy in the sky to help them out?
Speaking of which, you are preaching exclusively to computer users, who I am convinced fit the above 'emotionally secure' category. Meanwhile there are a lot of miserable, poverty stricken people elsewhere in the world who might be more receptive to comforting beliefs.
