The Sheperd's Grand-Daughter! Should we have the right to read it?

After reading the letter, I kinda felt angry because, "WHY CAN'T WE CHILDREN KNOW WHAT'S HAPPENING AROUND THE WORLD????" So what if it's effensive to christians?! I'm a christian and I don't feel effended! Instead I think the christians in the book were being too mean. Doesn't God tell us that every life is precious?; that God created all of us to care for each other and if we sin, we are always forgiven? What did the people in this story do to recieve this treatment? They having a peaceful life until the Isrealites came barging into their lives and starting a war for the land "God Gave Them". That is why I think they should let us know these events. It's not like we can't handle it. Besides we'll learn about this someday! So why not learn it sooner? GEEZE!!!!!!
