Harlan's opinion conflicted with the prevailing viewpoint of the Supreme Court regarding which issue?

Harlan's opinion, especially in the context of his famous dissent in the case of Plessy v. Ferguson (1896), highlighted his fundamental disagreement with the Supreme Court's endorsement of the "separate but equal" doctrine that legitimized Jim Crow laws. While the majority of the Court upheld the constitutionality of racial segregation, Harlan argued for civil rights and equality, emphasizing that the Constitution was color-blind and should not tolerate any form of racial discrimination. His stance was progressive for the time, advocating for the protection of African American rights in stark opposition to the prevailing legal interpretations that facilitated segregation and systemic racism. This distinct perspective on civil rights issues defined Harlan’s legacy as a champion for justice in stark contrast to the accepted norms of his contemporaries on the Court.
