What stereotype—prejudice, subordination, or discrimination—is the in-group challenging?
“No one gets through life alone. To some extent, we are all products of our environments. We learn from our families, schools, and cultures. Every person has to face severe challenges and conquer obstacles. How we face our challenges depends on how we are shaped by others and our strength of character.
Certain individuals in our society have played powerful roles in the evolution of prevailing norms. While we learn our culture from agents of socialization, great leaders with lofty visions lead people and nations in the direction of emancipation, economic prosperity, and political freedom. Each of the following speeches tells the story of a struggle and its leader. Each speech echoes the aspirations of thousands of people as well as their desire to change their social situations.
The purpose of this assignment is to demonstrate the power of stereotypes as a shorthand communication tool. With great economy of words, each speaker uses stereotypes to frame the audience into an in-group of which he or she is the leader and the out-group on the opposing side.
