PC - Political Correctness

Political Correctness means using words or behavior which will not offend any group of people. Most people think it is important for everyone to be treated equally, fairly and with dignity. Some words have been used for a long time that are unkind to some people. Sometimes these words have now been replaced by other words that are not offensive. Such words are described as politically correct. The term is often used in a mocking sense when attempts at avoiding offense are seen to go too far.
