Censorship involves the suppression of speech, communication, or other information that may be considered objectionable or harmful by a government, organization, or individual. It can include censorship of news, books, films, music, art, and online media and occurs for various reasons such as protecting national security, children, or certain political or religious views. While some countries have strong legal protections against censorship, these protections often require balancing other rights and determining what can and cannot be censored remains challenging.
