What is it about some Americans from Christian families that has enabled them to see through religion?

They have nothing. They had everything. There is your answer. If you are saying improved education then that would explain why I, and many Christian friends of mine are at the top of our years right? Why I and my friends have beaten Atheists and other faiths in education. I am not boasting, merely trying to show a counterexample your so called logic. You also cannot say that it is because I come from a poor school because you are including ALL atheists and Christians, meaning no matter what school it is, the atheists should be better. As for the ability to quesiton everything, do you really think that all Christians are always 100% in their faith. Even I have questioned it every once in a while, but no matter what, I always come back to the same thing. God is out there and God is my creator and I will serve him. I question everything trust me, so its definitely not that. If you find anything else that might be it I'l gladly show a counterexample again.
