Final answer:
The claim that citizens have rights and privileges guaranteed in the Constitution can be discredited by the fact that noncitizens can still claim certain rights and privileges in the Constitution. The passage also reflects the fallacy that African American people are inferior based on perceptions from an earlier time.
Step-by-step explanation:
The claim in the passage from the opinion of the court in Dred Scott v. Sandford, stating that citizens have rights and privileges guaranteed in the Constitution, is based on the idea that certain rights and privileges are exclusive to citizens of the United States. However, this claim can be discredited by the fact that noncitizens can still claim certain rights and privileges in the Constitution. For example, the Fourteenth Amendment grants equal protection under the law to all persons, regardless of citizenship. Therefore, the idea that noncitizens cannot claim certain rights and privileges in the Constitution is a fallacy.
Furthermore, the passage also reflects the fallacy that African American people are inferior based on perceptions from an earlier time. This fallacy has been discredited by the Civil Rights Movement and the subsequent legal protections and societal changes that have recognized the equality and human rights of African Americans.
