Words are changed so that meanings are hidden. Propaganda destroys the morals of the people because it undermines the basic foundation of all moral values — the truth. And the sad end result is that people often do not feel oppressed because they are thinking as they were taught to think — they do not see anything wrong in the world around them. They do not think for themselves because they have not been taught to think for themselves and it does not occur to them that they are entitled to think for themselves.
