In his letter, Luther King states: “If his pent-up emotions are not released nonviolently, they will seek to express themselves through violence; this is not a threat but a historical fact. With this quote, MLK wants to demonstrate two things. The first is the exceptional way in which blacks acted in non-violent protest, and the second is to make whites understand the consequences that can occur if no change is made. Luther King also states in his letter: “Oppressed people cannot remain oppressed forever. The desire for freedom will eventually come. This means that this segregation will end, he doesn't know when, but he knows it will end. And he's trying to tell the white population to stop this, to avoid violent protests. “There comes a time when the cup of endurance overflows and when men are no longer willing to allow themselves to be plunged into an abyss of injustice where they experience the sadness of corroding despair. » With this other example, Martin Luther King wants to explain that black people are also human beings and that there will come a time when their patience will run out and the way they act will be different.
