Back to the thread topic, one can assume that these same people that know essentially nothing about their religion, also do not take the time to analyze why they believe it in the first place. They are essentially accepting on sheer blind faith what ever pablum is being spooned out to them.
It is my assertion that this is the goal of the people who started Christianity.
1 Timothy 1
3As I urged you when I went into Macedonia, stay there in Ephesus so that you may command certain men not to teach false doctrines any longer 4nor to devote themselves to myths and endless genealogies. These promote controversies rather than God's workwhich is by faith. 5The goal of this command is love, which comes from a pure heart and a good conscience and a sincere faith. 6Some have wandered away from these and turned to meaningless talk. 7They want to be teachers of the law, but they do not know what they are talking about or what they so confidently affirm. 8We know that the law is good if one uses it properly. 9We also know that law is made not for the righteous but for lawbreakers and rebels, the ungodly and sinful, the unholy and irreligious; for those who kill their fathers or mothers, for murderers, 10for adulterers and perverts, for slave traders and liars and perjurersand for whatever else is contrary to the sound doctrine 11that conforms to the glorious gospel of the blessed God, which he entrusted to me.
Basically, what Paul is saying is "Pay no attention to that man behind the curtain."
Don't let the teachers of law fill your head with words of scriptures that you might actually learn something and ask questions... just accept with blind faith that which I'm telling you.
(and nobody can accuse me of taking the verse out of context. I posted the context.)
