Which factor contributed to Vincent's struggle for acceptance in society?

Vincent's struggle for acceptance in society primarily stems from his genetic makeup. In the world depicted in "GATTACA," society is heavily influenced by genetic engineering, leading to the belief that individuals with "designer genes" are superior. Vincent, conceived naturally and labeled as an "In-Valid," faces discrimination and stereotypes due to his perceived genetic inferiority. This bias manifests in various aspects of his life, from employment opportunities to social interactions, creating significant obstacles as he seeks to achieve his dreams. His journey highlights the broader themes of genetic determinism and the value of human spirit over biological determinism, emphasizing that acceptance should not hinge on one's genetics. Acknowledging this aspect of his struggle is crucial in understanding the societal dynamics present in the narrative.
