It is a standing insult tosportsmen to have to play undera rule which assumes that players intend to trip, hack and push their opponents, and to behave like cads of the most unscrupulous kidney. The lines marking a penalty area are a disgrace to the playing fields of a public school.

This [Magna Carta] has been forced from the King. It constitutes an insult to the Holy See, a serious weakening of the royal power, a disgrace to the English nation, a danger to all Christendom, since this civil war obstructs the crusade. Therefore†we condemn the charter and forbid the King to keep it, or the barons and their supporters to make him do so, on pain of excommunication.

This is not a book in the ordinary sense of the word. No, this is a prolonged insult, a gob of spit inthe face of Art, a kick in the pants to God, Man, Destiny,Time, Love, Beauty†what you will. I am going to sing for you, a little off-key perhaps, but I will sing.

-Miller, Henry Valentine

You have heard the sound of the white soldier's axe on the Little Piney. His presence here is†an insult to the spirits of our ancestors. Are we to give up their sacred graves to be ploughed for corn? Dakotas, I am for war.
