Zitkala felt oppressed in her new establishment because of the indignities shown to her. Let's explore the reasons behind her feeling of oppression:

Cultural Differences and Discrimination:
- Zitkala was a Native American girl who was sent to a white missionary school, where she was expected to assimilate into Western culture and abandon her native heritage.
- The school enforced strict rules and regulations that suppressed her cultural identity and forced her to conform to the dominant white culture.
- She was forbidden to speak her native language, practice her traditional customs, or express her cultural beliefs. This cultural suppression made her feel oppressed and robbed of her individuality.

Physical and Emotional Mistreatment:
- Zitkala experienced various acts of physical and emotional mistreatment at the school, which further intensified her sense of oppression.
- She was subjected to harsh discipline, such as corporal punishment, for minor infractions or for simply expressing her emotions.
- The school staff often ridiculed and belittled her native customs and traditions, making her feel ashamed of her heritage.
- Zitkala's long, beautiful hair, which held cultural significance for her, was forcibly cut without her consent as a symbol of assimilation. This act of humiliation deeply affected her and contributed to her feeling of oppression.

Loss of Freedom and Autonomy:
- In her new establishment, Zitkala had limited freedom and autonomy over her own life.
- She was separated from her family and community, which caused feelings of homesickness and longing for her mother's presence.
- The strict rules and regulations imposed by the school limited her choices and suppressed her individuality.
- Zitkala's personal experiences and emotions were disregarded, and she was expected to conform to the expectations of the white society.

Overall, Zitkala felt oppressed in her new establishment due to the cultural suppression, physical and emotional mistreatment, and the loss of freedom and autonomy she experienced. These factors collectively created an environment that made her feel marginalized and oppressed.
