In his “Letter from a Birmingham Jail,” who is Dr. Martin Luther King Jr. disappointed in and why?

Dr. Martin Luther King Jr. is disappointed in the white moderate clergymen who criticized his campaign of nonviolent protest and civil disobedience in Birmingham, Alabama. He believed they were more concerned with order and preserving the status quo than with the injustices and oppression faced by African Americans. Dr. King felt they were too passive and indifferent to the suffering of Black people, and he urged them to take a more active stance in supporting the fight for civil rights.
