The correct answer to this open question is the following.
Although you forgot to attach the excerpt, doing some research we can say the following.
Justice is not an idea. It must be a reality.
When Martin Luther King Jr. received the Nobel Peace Prize. he delivered an emotional speech that reminded all the injustices he and the African Americans -other minorities as well- had to suffer in their civil rights fight.
I want to compare those ideas with something that has happened in my life.
I was not well-accepted in the athletic team in high school. Could it be my race, my ethnicity, my personality, whatever! The thing is that other colleagues spoke at my back. They did not inform me about important issues for the team. The coaches were not interested in me as an athlete or as a student. It was a difficult time.
Although it could be a minor case compared with what the African American people lived in the 1950s and 1960s in the southern states, that affected me.
Mr. King said the following in his speech:<em> "I refuse to accept the idea that man is mere flotsam and jetsam in the river of life, unable to influence the unfolding events which surround him. I refuse to accept the view that mankind is so tragically bound to the starless midnight of racism and war that the bright daybreak of peace and brotherhood can never become a reality."</em>
And those ideas really impacted my personal experience because I refused to be treated as a second class citizen. His ideas gave me the strength to strive and be perseverant.
That is why I invite all students to never surrender. To be grateful for what they have and do not let anybody tell you otherwise. Every single human being is of so much value.
