When somebody plants a bomb, then proceeds to put as much distance between himself and that bomb as possible, it is permissible to call that person a 'coward'. (Although the term that I would most likely use is 'smart') However, you cannot - if you wish to use the English language correctly - say the same of a suicide bomber. It takes a lot of balls to do what these guys did. You may call this attack a lot of things, but taking control of an 'enemy' plane and smashing it into a skyscraper -- sacrificing your own life to defend your ideas -- can not under any circumstances be considered 'cowardly'. Fanatical?... yes. Suicidal?... Yes. Horrendous?... yes. Cowardly?... No way. Our enemies may be a lot of things, but cowards they are not.
What other newspeak have you noticed in today's society?
