This was true in my case, particularly my high school years. On some level I knew that what I was being taught contradicted my faith, but I was unable to explicitly identify and resolve the contradictions floating around in my mind.
But I was fortunate enough to experience and identify my state of mental anguish, even if I couldn't find a way to free myself of it. In other words, at least I was angry, even if I didn't understand why. Unfortunately, most children learn to live with this cognitive dissonance by adopting a generally indifferentist and agnostic position regarding life itself. I'm convinced that this explains teenage ennui.
The purpose of life for all people is to know, love and serve God in this life and to be happy forever with Him in the next. Any purported education that claims to prepare children for life, yet neglects the central purpose of life, is child abuse of the highest order.
What people should know is that the U.S. Constitution does not mandate a liberal, secular humanist, statist tyranny over education. The only reason we have this situation in America is because of bigotry. The moronic secular humanism of the NEA which casts a shadow over most of the education in this country should be ended. And that can be ended with school choice for EVERYONE.
I am amazed and appalled at the everyday subtle influences of evolutionary and Marxist teaching....I try to find them and point them out....very PC-incorrect! I was at my brother's house the other day and saw his dogs. The thought ran through my head about 'their wild undomesticated predecessors.' That wasn't exactly a Genesis Chapter 1 thought--nor scientific. I caught myself. Do most kids have the knowledge to identify cognitive dissonance these days? Only the kids of any Republican psychologists and group therapists in Florida whose parents are making book on DepressedoCrats there.... (wry grin)
