This list consists of some of the most widely known authors and playwrights. Why is their work censored? Haven't we been reading them for decades, or even hundreds of years? Why were they never censored before? I think we all know that the writing did not become "bad" overnight. Instead, it is society's ignorant perspective that children need to be guarded against the thoughts and actions in these books. In my opinion, parents and other censors are not particularly worried about their children. That is only the cover up. The truth is that they are scared for themselves. They cannot think of living in a world where thought is constantly questioned and children are enlightened philosphers. How sad...are these censors jealous that kids want to read this material? And how can the future of our country succeed if the foundations written in books are censored? How will kids ever know how to run a country?So many questions, and so little answers. This is censorship
