That's exactly how I feel about it. Since they don't understand it and don't want to, why don't they just leave it alone? It's because Satan has told them to try to bury it.
Why do you assume not believing is the same as not understanding?
The Bible is essentially taking advantage of your pride and vanity, "other people don't understand this book, but you do because your special and you have something they don't." Yet you're the ones that call us arrogant.
I believe many atheists don't have a problem with people reading a spiritual book if they would apply it to their lives and not try to make it rules of this world.
There are those who want to see everything according to how that spiritual books reads. So, it makes sense for those who do not understand spiritual things to educate themselves on as much as possible for when they encounter those who do, who push those beliefs on them.
If theists understand spiritual things how come they have so much trouble explaining things when we ask? How come they can never seem to come to an agreement on anything? Their answers are always all over the place, as if they're just making it up as they go.
