Answer:
Dr. King develops the claim that racial injustices must be uncovered to be healed by highlighting the need for a relentless pursuit of truth and justice. In his famous "Letter from Birmingham Jail," he states, "Injustice anywhere is a threat to justice everywhere" and emphasizes the interconnectedness of all individuals and communities. This statement supports the claim by asserting that racial injustices cannot be isolated incidents but are part of a larger system that requires examination and correction. Furthermore, Dr. King provides specific examples, such as the unjust treatment of African Americans through segregation laws and the denial of basic civil rights, to illustrate the pervasive nature of racial injustice. By exposing these instances and calling for their rectification, he strengthens the argument that true healing can only occur when the underlying injustices are brought to light and addressed.
