I apologize for the confusion, but yes, it is correct that the Supreme Court case Plessy v. Ferguson reaffirmed and strengthened Jim Crow laws in the South. The case upheld the constitutionality of racial segregation under the "separate but equal" doctrine, which allowed for racial segregation in public facilities. This decision had a significant impact on maintaining and institutionalizing racial discrimination in the South for several decades.
