Why was Jeanne terrified of moving to terminal island in Farewell To Manzanar?

Farewell to Manzanar is ultimately a story about coming to understand one’s place in the grand scheme of culture and society. Jeanne, a young Japanese girl in the memoir, is entirely American—but because of her racial and ethnic heritage, she is thrust into an internment camp and forced to exist with the label of the enemy of America. The story focuses on Jeanne coming to terms with how her country treated her, the desire to be accepted by mainstream American culture, and how to honor her Japanese heritage.
Strangely enough, Jeanne wouldn’t have come face to face with much of her Japanese heritage if it hadn’t been for the internment. Before the release of Executive Order 9066, Jeanne and her family lived in Ocean Park—a white neighborhood. Jeanne’s father had moved her away from Japanese people, and she never learned to speak the language. It was her father’s eventual arrest and the growing anti-Japanese sentiment that forced her family to move to Terminal Island with other people of Japanese descent.
Jeanne, growing up in a majority white neighborhood, was afraid of anyone who looked remotely Asian. She knew her family, of course, but everyone else was a potential threat. The reason she was terrified relates to what her father would tell her,

This was partly Papa’s fault. One of his threats to keep us younger kids in line was, “I’m going to sell you to the chinaman.” When I had entered kindergarten two years earlier, I was the only Asian in class. They sat me next to a Caucasian girl who happened to have very slanted eyes. I looked at her and began to scream, certain Papa had sold me out at last. (Chapter 2)

Jeanne’s father instilled a fear of Asian people in her by using them as a boogeyman who preyed on bad children. Along with that, Jeanne was terrified because she didn’t fit in—something that would be a large part of her struggles later in the story. Jeanne didn’t speak Japanese, and the other children on Terminal Island would torture her relentlessly because of it. She was cut from a different social class, and the divide was almost too great for others to forgive.
Ultimately ,Jeanne’s fear would be understood as silly, but they are symbolic of the rent she feels from her Japanese heritage. She goes on to disappoint her father in different ways because she is not entirely “Japanese” enough for him. Despite that, she finds a way to appreciate her heritage while also living a life that is true to her experience as an American.
