Where do I begin with such a touchy subject? Let me just say that you, the reader, have the freedom to choose what you read. We all have the freedom to adopt what we read as our own opinion(s) or to let it go by the wayside and even kick it to the curb. You are in control of what enters your mind. Free agency at its’ best gives you the capability to pollute or adorn your mind with what you deem worthy of your attention, whether it be in your opinion, wonderful or horrible. The mind is a wonderful thing. So choose wisely and don’t let it go to waste.
In my opinion, books should never be banned. I also believe that it is up to parents to teach their children right from wrong so that if they do happen to come across something that differs from the values they were taught, the child will know the difference and the fictional will not so easily become fact. They will be able to form opinions for themselves, to think of the consequences of the characters in the books and draw conclusions for themselves when relating it to their life.
I must also say that as parents it is a tough decision to make. It can be difficult to choose what we read to our children, to help them choose what to read when they are too young to choose for themselves what is appropriate for their age and understanding. I think it is safe to say that most parents naturally wonder from time to time, “will my child understand this topic or will it confuse them,” I know I do. So in a nutshell here is my opinion on the subject:
A Pen In Neverland 
I agree with you 100%. What bugs me the most is that people just don't want their kids to read a book but no one's kids should read it! Or the person wanting to ban the book has not read it and is relying on hearsay. As for favorites Harry Potter. bilbo48
