What inference was King making in his "I Have a Dream" speech about the progress of African Americans in entering the mainstream of Ameican life?

Unlike
more militant African American civil rights campaigners such as Malcolm X, Martin Luther King
believed that integration was the way forward. He believed that once the system of desegregation
had been dismantled, African Americans should take their rightful place in mainstream
society.

In a notable passage from his famous speech, King explicitly states
that the destiny of African Americans is tied up with that of white Americans. Far from being
inherently antagonistic, the freedom of the two races is inextricably bound together. Fighting
for the civil rights of African Americans, King believes, means fighting for everyone's
rights.

King's radically multicultural vision is brought out later on in the
speech when he expresses his hope that, one day, in Alabama, the spiritual home of the civil
rights movement,

little black boys and black girls will be
able to join hands with little white boys and white girls as sisters and brothers.
