By using parallelism in her speech, Shirley Chisholm illustrates her trust in people and her dedication to be a champion of all people. Parallelism is the repetition of grammatical structures for emphasis and clarity. In this case, Chisholm repeats the structure "I believe" to highlight her core beliefs. This repetition emphasizes her unwavering faith in the American people's ability to correct mistakes and recognize the talents of all Americans, including women and minorities.
Therefore, the idea Chisholm illustrates through parallelism is her trust in people and her dedication to championing the rights and talents of all individuals, regardless of gender or ethnicity. This aligns with her commitment to promoting and supporting women and minorities, making her campaign a symbol of inclusivity and equality.
