How effective is the argumentative structure that King uses to persuade his audience? Use details from the text to support your answer.

The letters by Dr. Martin Luther King Junior addressed people and inspired people by mentioning the "legal" acts done by Adolf Hitler in Germany and "illegal" freedom movement in Hungary. He wanted the audience to understand and differentiate between justice and injustice caused by the governments themselves, and he inspired people to take action. He called the step as "urgent" and motivated people to stop segregation and unite and take action against it. He used simplified language to sow the actual intentions of the non-violent measures taken by the white people, which were causing injustice to the non-whites.
