Explanation: This powerful line is from Martin Luther King, Jr.'s "I Have a Dream" speech. It encapsulates the core vision of the Civil Rights Movement: to create a society where racial prejudice is eradicated. King personalizes this grand vision by focusing on his own children, expressing a universal parental hope for a better world. He dreams of an America where an individual's worth is measured by their moral qualities—their integrity, compassion, and abilities—rather than by the superficial factor of skin colour. It is a timeless appeal for equality and a society that values inner substance over outward appearance.
