Miami is definitely the most culturally diverse city I have ever lived in, but somehow, people still manage to judge. During my first year here, the kids used to make fun of me for having a British accent because of my studies in a British school in Madrid. I even got made fun of for my Spanish accent when I spoke Spanish because of the lisp the Spanish have when they speak (compared to many of the local Cubans). In the other countries, I was judged for the people I spent my time with. But in the United States, I was the source, and it felt different.
Once formed, enemy images tend to resist change, and serve to perpetuate and intensify the conflict. Because the adversary has come to be viewed as a "diabolical enemy," the conflict is framed as a war between good and evil. Once the parties have framed the conflict in this way, their positions become more rigid. In some cases, zero-sum thinking develops as parties come to believe that they must either secure their own victory, or face defeat. New goals to punish or destroy the opponent arise, and in some cases more militant leadership comes into power.
