What is the theme in Strangers from a Different Shore: A History of Asian Americans by Ronald Takaki?

Discrimination and prejudice are a major theme of the book, with examples in every chapter. The Asians were not accepted as Americans even if they were native born Americans. They were considered to be strangers. This was an experience that the author, Ronald Takaki, himself had. He was born and raised in Hawaii in a community comprised of people from different ethnic backgrounds.
