What is the author's style in I Have a Dream: Writings and Speeches That Changed the World by Martin Luther King?

Dr. Martin Luther King Jr. had endured racism for many years. Most of the book consists of his speeches and writings that were given from the viewpoint of a person that had been looked at as a second class citizen with less rights than others in the same society. Dr. King was also a preacher, and while he urged people to fight for their civil liberties he also urged them to realize that God has called all of his people. The life and background of Dr. Martin Luther King Jr. is easily seen in his writings, although he doesn't spend much time explaining what his life was like. He also studied the teachings of Gandhi in depth and the reader sees that the reoccurring theme in Dr. King's writing is nonviolent protesting and needing to keep good relationships with those that opposed them.
