An interesting thing occurred to me while watching Hook--the Robin Williams version of Peter Pan with my daughter. That movie is completely engulfed with fantasy--which of course, is a fun thing for children.
One thing was common throughout the movie: the children (and a few adults) kept fantasizing and speaking of myths, and the dad (Robin Williams) was viewed negatively for correcting them and telling them truth about these silly myths.
It suddenly occurred to me that a common theme among fantasy-type movies, is that it's always the 'bad guy' or the 'mean one' or even the 'stupid one' that doesn't believe. Not believing is seen as ignorance or negativity.
And that's the key in all these movies--to believe. The one (or ones) that don't believe are either bad, stupid, completely miss out on everything wonderful, or eventually become convinced and believe as well.
Subconsciously, this must be teaching children a positive association with belief and a negative association with challenging belief. This must also play a role in the way adults view the hope of their own beliefs, and their negative views of Atheists for doubting those beliefs.
But, that's just one blogger's observation.
