Kim's line of reasoning uses historical examples to prove her point: That Home is where the Han is. She integrates Korean culture on her essay by combining Korean words such as "han" into her work, but clearly defines it so the essay is understandable to people who are not Korean. She defines han as the sorrow and anger that grow from the accumulated experience of oppression.
Then Kim goes on to tell why the United States has become home to people from a Korean background, the different examples of "han" that they have experienced. She tells about the Los Angeles riot, and the unfair blame that was put on the Koreans, and she talks about the experience that many Koreans had trying to become American. She also tells about how life was in Korea, not much better than it is in the U.S.
Then she tells about her personal experience with prejudice, the hate mail she recieves after being published in newsweek.
The text's underlying assumptions are that every one who is not Korean is prejudiced against Korean's and this implies that she is writing to try and change every one's opinion. Personally I assume that not many people are prejudiced against Koreans becuase I have never seen this this racism, nor heard about it before. In fact in my limited experience, in my taekwon-do class the Korean students are treated better, and given special attention because it is assumed that they will be naturally talented at martial arts. This essay really opened my eyes to the prejudices and taught me about history, not only of Korea, but of the U.S., however it did not change my opinion about Koreans as an ethnic group, becuase I was not the target audience for this essay.
