Are there not some books that should be banned? Who should decide when something is "age appropriate" for you? For people in Canada?

Let me start off by saying in my opinion no book should ever get banned for any reason. I see no point at all in banning a book because if you think about it what is written in these "banned books" is the thoughts of someone, so why are we banning it, what ever happened to freedom of speech? Why because its written on paper the government has the right to ban it? I think that's a bunch of bologne, a lot of these "banned books" are really good pieces of literature meant to entertain the mind and generate thought. None of these books were made especially to harm society or any certain individual, so why are we banning them? The practice of banning a book is a form of censorship, which in Canada you would be surprised to hear there is a lot of. The Canadian government usually will ban a book if it has material that are about sexuality, race, drugs, social standing, or if they feel it affects "public safety". But really though how is a book going to affect public safety, it really doesn't make any sense to me. Think about this one folks and Stop Banning Books seriously it makes no sense. Kyles advice for this blog thought Stand up and let everyone know I READ BANNED BOOKS.
