"Many others can easily argue that accepting the entire Bible as fact is naive and ignorant."
They could offer their opinion - but it is not a good comparison.
That the Bible has historical accuracy among other things is not really debateable.
That parts of the Bible require the same leap of faith to beleive for children, adults, the uneducated, the scholars and scientists - is not by definition 'ignorance', but a combination of simple faith and personal experience.
Most Christians understand this requirement of faith to be a corner store of our relationship with God\Jesus. Would it be right if to understand the Bible and attain a solid 'faith' in God, you had to have years of formal eductation? The beauty of the Bible and understanding God\Jesus is that a small child can have that personal relationship with Him through the simplest faith, and a Dr with many Phd's can study every translation, research the historical contexts, examine the archeological evidence, and yet in the end they must take the same step of faith. Why? Because time and again in the Bible God\Jesus demonstrates that it is not by OUR efforts (studying\being smart\intelligent, 'being good', doing all the 'right things', being very 'religious', being a 'good person', etc), but the perfect work of Jesus that gives people the opportunity\gift of salvation.
Of course there are some very confused, ignorant, dillusional, mislead individuals and even entire congregations of "Christians" who cast a bad light on all Christians and religious people. But that is simply a matter of the diversity of mankind. Pick any large group of people and you can quickly find the deviants, ignorant, dillusional, etc...
