Our way of living together in America is a strong but delicate fabric. It is made up of many threads. It has been woven over many centuries by the patience and sacrifice of countless liberty-loving men and women. It serves as a cloak for the protection of poor and rich, of black and white, of Jew and Gentile, of foreign and native born. Let us not tear it asunder. For no man knows, once it is destroyed, where or when man will find its protective warmth again.
