When you said we must have self-respect, i wondered how we could have self-respect and remain patient considering the treatment accorded to us through the years.
this excerpt contains an historical allusion to
a. civil rights activists that advocated for equal rights in the united states throughout the 20th century.
b. the discrimination and bigotry faced by african americans throughout history in the united states.
c. robinson’s belief that an end to segregation is impossible to achieve in the united states.
d. robinson’s belief that president eisenhower is responsible for ending segregation in the united states.

This is part of a letter written by a famous African American, Jackie Robinson.

Considering that he talks about having patience, or not having, and the mistreating of "us" as a group, we can discard anything about activists. Generally, and obviously, blacks were not defenders of segregation and the letter doesn't bring up anything directly about the president.

In fact, he is generally speaking about how his ethnic group has been badly treated throughout the years. So the answer is:

B. the discrimination and bigotry faced by African Americans throughout history in the United States.
