Observation 4: Preparing for MLK's letter

In the first paragraph MLK says he does not usually pay attention to criticism but will respond because he respects his criticizer. Readers can see that he is not bothered by other people's negative criticism and keeps tries to keep his head up. He appeals to the emotions of the audience by saying he is in Birmingham because there is injustice and unfairness there. Unfairness appeals to the audience because most people cannot stand the thought of not being treated the same as others. King used several metaphors, shadow of deep disappointment, for example. These metaphors appeal to style because they help the audience better understand the points that are being made.
