Final answer:
In 'Mixed Blood' by Fish, the comparison between the Masai and Pygmies represents the tensions in cultural identities and the lasting impact of culture on fostering mutual hatred and violence.
Step-by-step explanation:
According to Fish in 'Mixed Blood,' the striking contrast between the tall Masai and the short Pygmies symbolizes the tensions that arise as characters navigate an identity encompassing both African and American elements. This imagery is used to highlight the complexities and sometimes the tragedy found in the clash and interweaving of different cultures. The contrast is also indicative of the broader theme that cultural power can perpetuate mutual hatred and violence even many generations later, overshadowing the shared humanity and common ancestry of the groups involved.
