Censorship is not just about forbidding discussion of certain facts or limiting the freedom of thought. Our very patterns of thought, emotions, and beliefs can be molded in ways beyond our control, both directly and indirectly. Censorship is indirectly imposed through instilling feelings of guilt and fear through the media and institutions of society. For these reasons, censorship is a violation of human rights. Political discourse and artwork have been subjected to censorship in the same ways for thousands of years.
There are many examples of censorship imposed on artworks of all kinds including books, movies and plays. Sharing a few here will show how censorship can become irrational.
