Why is America so religious?

[helmespc]

I think a big difference between the US and the European nations is that the US is MUCH more spread out.... even though some bastions of reason exist, its really hard for them to cause a "reason" mob mentality to sweep across the nation because there's just vast swatch of "uninhabited" ignorant land that essentially act as a "reason insulator"... Intercity drives in the US generally require at minimum hour of travel across these no man's lands... its hard for culture to traverse these buffers. Radio, TV, and internet has made it easier, but it will be a long time before people living in the outskirts are educated enough for a culture of reason to truly flourish... I may be totally off base, but I truly believe geography plays a large role in the ignorance of american culture.
