Final answer:
Justice Taney's claim that black people were not citizens and inferior is countered by the lack of evidence, the freedom of emancipated people, and the fact that ancestry does not determine citizenship.
Step-by-step explanation:
In the case of Dred Scott v. Sandford, Justice Taney argued that black people were not included under the word "citizens" in the Constitution and therefore did not have the rights and privileges provided for citizens. A counterclaim to this argument could be that Taney failed to provide any actual evidence for his statements that black people were universally considered inferior. Without concrete evidence, his claim of black inferiority lacks credibility.
Furthermore, it is important to note that Taney's argument about emancipated people still being controlled by white people is false because once emancipated, individuals were legally free and no longer subject to the authority of their former owners. Finally, Taney's argument that black people were not citizens because their ancestors were forced to come to the United States is also false, as citizenship is not determined by an individual's ancestry but by their legal status as a member of a state or nation.
