Martin Luther King was the leader who combined extreme ideas, political mind, and rhetorical brilliance; despite King's challenge, he remained a supporter of nonviolence and described his vision of racial equality in the United States.
Martin Luther King made great success in eliminating ethnic discrimination against blacks
King has had a great success in eliminating the racial discrimination and marginalization of Afro-Americans (Americans of African descent) as well as the economic gap that existed between whites and blacks
I wholly support peaceful non-compliance with unjust laws. However, be careful of giving him undue credit. If memory serves, significant statistical progress in the area of racial wealth disparity stagnated and began to regress when government stepped in to write laws in the area of civil rights and ramped up welfare programs. The legal system and broken education system definitely marginalize minorities today, too.
We are all leaders beloved... Trust me.
