Why Are Americans Resistant to Science?
Here is a simple answer for those who have the stomach for it. Americans have a highly-developed sense of self-preservation, just like donkeys (coincidence I am sure).

Their religion is the defining aspect of their sense of self. They will never-ever knowingly let anyone violate that sense of self.

So there are two way to make Americans more science-minded. One is by deceit. But then they will use deceit to spread religion in the name of science, like Kent Hovind did.

Then there is the straight and narrow path taken by Richard Dawkins here. Make science the method by which Americans defend their sense of self-preservation. The worst thing that can happen then, is that they will find some poor third world country to attack because they have proper religion and improper science in their schools.
