Banned Books

Something that really bothers me in the education system is the removing of books from school libraries. I think it is unreasonable the reasons why certain books are removed from school libraries. I understand that if the material in the book is not developmentally appropriate for the age of the children using the library; there should be restrictions for this. However it seems like some books are removed simply because some parent didn't like them.
As a student, I suppose I have a different point of view on this subject than a parent would. I read a lot of books when I was younger. When looking at a list of commonly banned or challenged books, I realized that I had read four out of the top five books before my freshman year in high school. I believe that each book that I've read has affected me in some way or another. I appreciate this and think I've grown from that.
I think that lots of times when parents want books removed from a library it's because they are worried that the beliefs and values they taught their children won't stick. I think that parents need to be confident that the values, etc. they instilled in their children will be present even if they are challenged by a book. I don't think books should be removed from libraries simply because parents are scared of what it may make their child think.
