Answer:
In "Letter from Birmingham Jail," Dr. King develops the claim that racial injustices must be uncovered to be healed by arguing that the stress caused by direct actions is necessary to expose and confront the hidden tension and injustices already present in society. Dr. King supports the claim by using vivid imagery, such as the metaphor of the boil that must be opened to be healed, it makes people see how ugly the reality of racial injustice is. One example that supports his claim is found in paragraph 7 where Dr. King writes, "Like a boil that can never be cured as long as it is covered up but must be opened with all its pus-flowing ugliness to the natural medicines of air and light, injustice must likewise be exposed." This shows how hidden injustices must be brought to the surface before they can be healed. Another specific example is found in paragraph 8 where Dr. King writes, "Now is the time to lift our national policy from the quicksand of racial injustice to the solid rock of human dignity." Here, Dr. King argues that exposing and confronting racial injustice is necessary in order to transform national policy and maintain the dignity of all individuals. This example again supports Dr. King's claim.
