But why is that the case?
Europe has a much less biased media there is something there.
Education is a factor.
But there is still something missing in the picture.
The military industrial complex, manifest destiny, a profit based media oligopoly.... Take your pic. There's no simple answer but the literal belief many Americans have in the bible is a start. Then they start to believe the literal meanings of their constitution and BoR. that's how the 2nd amendment mess has stayed alive.
Allegory, inference, analogy, et cetera are lost on my neighbours to the south...
