> but I don't know why similar charity isn't awarded to books that aren't the bible.

I‘m not sure what you‘re saying here, as the Bible is almost nationally “banned” from public school libraries due to the belief that so much as including it in a library is a literal violation of our country’s founding principles. If you mean why do parents who request books to be “banned” typically give charity to the Bible, while not giving the “banned” books the same charity, then in major part it’s because they are incomparable. The Bible is the book that has led us to where we are today; it led men to found nations, find unity with their fellows, and strive to create a better world. It is a book that has survived and thrived for over 2000 years, and is possibly as old as 8000 years. Additionally, if we wish to be less charitable, then it is because the Bible is the cornerstone of their worldview, just as many who decry “bans” find said books to be cornerstones of their worldview.

Finally, the majority of children are NOT exposed to the sections of the Old Testament you are quoting, or they have been redone (see Veggietales), and most parents, many who would request certain books be “banned”, would agree that those stories are not appropriate for children. The majority of biblical education is focused on the New Testament, which is historical and lacks many of the “colorful” descriptions that the Old Testament typically provides.
