Final answer:
The text from 'A Genetics of Justice' by Julia Alvarez suggests that the lasting effects of injustice, such as habits of repression, censorship, and terror, are difficult to correct as they can persist internally even when external conditions have changed, echoing the prolonged psychological impact of living under a dictatorship.
Step-by-step explanation:
The evidence from the text that best supports the central idea that the lasting effects of injustice are not easy to correct is the author’s depiction of her parents’ inability to exercise their First Amendment rights due to their ingrained fear from years lived under a dictatorship. The excerpt from "A Genetics of Justice" by Julia Alvarez clearly states, "All their lives my parents, along with a nation of Dominicans, had learned the habits of repression, censorship, terror. Those habits would not disappear with a few bullets and a national liberation proclamation." This illustrates the profound psychological impacts that repression can have on individuals, lasting well beyond the physical removal of an oppressive regime and into their new lives in a country that legally upholds free speech.
The mentioned habits of repression, censorship, and terror do not easily lift with a change in environment or legal systems since they have been deeply instilled through years of living under a dictatorial regime. Furthermore, Alvarez's reference to her parents still living "in the dictatorship inside their own heads" even after moving to New York with its free speech protections highlights the internal struggle individuals face as they cope with post-traumatic stress from past political oppression.
