Though both Martin Luther King, Jr. and Malcolm X both
worked on the goal of helping blacks in their struggle for civil rights in the United States in the 1960s,
their approach and speech was very different.
Martin was more conciliatory in his approach. He used peaceful methods and often
incorporated the teachings of the Bible.
He wanted blacks and whites to coexist with each other. Malcolm on the other hand, was very
aggressive in his approach. He was not
afraid to lash out at what he viewed was the unfair treatment that blacks were
given and encourage violent means to achieve that goal.
