By the time I was twelve, I'd read through most of the children's room books in our small library. I wanted to read Gone with the Wind. The head librarian actually called my grandmother to see if it was all right for me to check it out. (Of course, she said yes!) I don't recall it being particularly racy - but I did love it! And, even if I hadn't been allowed to check it out, I would've spent some time in the stacks reading it!
Banning books isn't going to stop them from being read. If you want to read a banned book, it would be nearly impossible to NOT find it. And, if you find it - you're going to read it!
Fear is the motivation behind book banning. With parents in particular - the fear of losing control over their children. Well... as a parent with grown children, I can categorically state - you will eventually lose control! And, those children will have their own ideas, they'll make up their own minds, and they will live their own lives. However, if you want to be a part of that process - reading these books alongside your children & discussing the ideas found within will do more to cultivate understanding and to forward the education and enlightenment of our kids.
Book banning - I'm agin' it!
