Rosa Parks refused to surrender her bus seat to a white passenger. At the time, white-privilege was real. Rosa, because of her color, was supposed to give up her seat to any white passenger who requested she do so. Rosa, knowing this was unfair, unequal, and inhumane, refused to move. She stood up for herself, and although she may not have known it at the time, for her people. She would accept nothing less than what she deserved.
In "Letter from a Birmingham Jail", MLK writes about injustice and inequality. He defends his race, loved ones, and religion. King expresses how unfair the treatment his people receive is. MLK then proceeds to explain the reasoning on why all of this should stop. He saw the inequality, and took the initiative to do something about it. King refused to take anything less than what he deserved (for himself and for his people).
In the tragedy "Antigone", Antigone defends her brother after his death. Creon, Antigone's uncle and the ruler of the land, has banned anyone from burring Polynices. Antigone believed that this was unfair, so she gave Polynices the respect she thought he deserved since he couldn't do it for himself. We should do unto other as we would want them to do to us, and we all want love and respect. Therefore, when given the opportunity, give others what you know you deserve.
