Censorship is the name for the process or idea of keeping things like obscene word or graphic images from an audience. There is also such a thing as self-censorship, which is when you refrain from saying certain things — or possibly re-wording them — depending on who is listening."
"to remove anything offensive from books, films, etc., or to remove parts considered unsuitable from private letters, especially ones sent during war or from a prison:"
You try and choose a meaning to support your argument just as much as anyone else does. Welcome to terminology.
