How did martin luther king jr influence his readers in the "letter from burmingham jail"?

Considering the context of its creation, the "Letter from Birmingham Jail" is remarkably restrained in tone. Throughout his career, many critics of Dr. King argued that he was too deferential to the white authorities that facilitated segregation and other racist policies, but the tone here seems to serve several purposes. First, it conforms to his ultimate purpose of justifying his cause as being in the name of justice. He does not wish to validate his audience’s deep-seeded fears - that the black movement is an extremist set that will engender violence. Therefore, by utilizing restraint, he earns a sympathetic ear to which he then declares his proud embrace of extremism and tension. His difficult arguments end up practically unimpeachable precisely because he has presented them through logos as well as through pathos. However, the restraint also allows him to reinforce one of the letter’s central themes, the interconnectedness of man. There are times when he distinguishes himself and his cause from that of his opponents, particularly in terms of race. However, he for the most part suggests that all men are responsible for all others, an idea that would not be as effective if the tone of the argument was too fiery and confrontational.

The Letter from Birmingham Jail, also known as the Letter from Birmingham City Jail and The Negro Is Your Brother, is an open letter written on April 16, 1963, by Martin Luther King Jr. The letter defends the strategy of nonviolent resistance to racism. It says that people have a moral responsibility to break unjust laws and to take direct action rather than waiting potentially forever for justice to come through the courts. Responding to being referred to as an "outsider," King writes, "Injustice anywhere is a threat to justice everywhere".
