Although Martin Luther King's personal life was criticized, he did well in the civil rights movement because he actively defended the rights and honors of African Americans. This led many people to choose assassination to get rid of Martin Luther King, but it didn't succeed in the end, because Martin Luther King was very influential at that time. If Martin Luther King is dismissed at will, it will lead to more riots and make the United States very unstable.
So Martin Luther King did a very great thing. Without him, the status of African-Americans cannot be greatly improved. Although there is still very serious racial discrimination in the United States, it is much better than then, so Martin Luther King did a very great thing. Without him, black Americans are still a discriminated race.
Therefore, many other colored people also worship Martin Luther King. Without him, other colored people will still accept the rule of white people and will not choose to resist at all. Martin Luther king aroused strong resistance from people all over the world at that time, which made the civil rights movement go on vigorously all over the world at that time.
