Throughout the history of United States, racism appeared a lot of times. One example of racism can be found when we look on the US's involvement in Vietnam during the war. During the war there were there was a lot of anti war movements, and many people was against this war. One of them was Martin Luther King. " We will be marching for these and a dozen other names and attending rallies without end unless there is significant and profound change in American life and policy. Such toughts take us beyond Vietnam, but not beyond our calling as sons of the living God" (9) This qoute is from speech that he gave on April 4, 1967 at Riverside Church in New York and it's also a good example of King's opinion about our involvment in Vietnam war.
