A big problem with Christians is the disregard for anything that contradicts the bible. I've grown up hearing about how the scientists are wrong in one ear, and yet science has brought us so many useful things. I've heard criticism, like the scientists are always going back on what they say. When that is a good thing, a self-correcting knowledge base is much better then one that refuses to budge and instead offers explanations when something doesn't fit. I could go on, but really, if someone chooses to believe folklore and myths from thousands of years ago over a system that searches for facts and ignores things that can't be proven, then they are ignorant and are only slowing the human race down.
