"I early learned that it is a hard matter to convert an individual by abusing him, and that this is more often accomplished by giving credit for all the praiseworthy actions performed than by calling attention alone to all the evil done." (paragraph 9 of Two Thousand Miles for a Five Minute Speech)
Very insightful, Mr. Washington. It seems as though this statement is why he was so successful in his speeches and reaching people from different cultural backgrounds. If you attack those you're trying to reach, you will never reach them. He made himself neutral, and praised all the good being done instead of the bad. By doing so, Washington created a positive receptive audience who was eager to hear his message. When giving his big speech, it was in front of a large group of people, those for and opposed to him. Through stating the positive and never attacking anyone, he reached everyone! This is an excellent read for anyone, especially in this aspect.
