Well, as you know, this kind of mindset is the most effective way to deal with the phenomenon of cognitive dissonance. When you’ve trained a group of individuals to be completely obedient, then there is largely no such thing. Only engagement at a relatively intellectually deep level with the outside world can change that. Which is why we have such a thing as Christian colleges.
I should add, since my post ended too quickly, that the reason there are Christian colleges is so Evangelical leaders can avoid that kind of engagement. It also explains a large segment of the homeschooling movement.
