Here's the difference, I don't need any of recorded History to be true, I'm not basing my current life around a belief system where-in any particular piece of history HAS to be true in order for my belief to hold, I'm not threatened when they find counter evidence to History as we know it, I'm not required to defend Platos existence, I don't need him to have existed.
All of these things are a preresiquite for Biblical belief, it HAS to be true to believers, it HAS to be accurate, believers feel threatened by counter evidence, they HAVE to defend the Bible lest their belief system crumble to ashes, their very way of life depends on these things.
It's quite sad/pathetic really, to have faith you HAVE to be ignorant of so much.
