Which part or parts of the 14th Amendment would force states to protect the rights in the Federal U. S. constitution?

The Fourteenth Amendment contains a number of important concepts, most famously state action, privileges & immunities, citizenship, due process, and equal protection-all of which are contained in Section One. However, the Fourteenth Amendment contains four other sections. Section Two deals with the apportionment of representatives to Congress. Section Three forbids anyone who participates in "insurrection or rebellion" against the United States from holding federal office. Section Four addresses federal debt and repudiates debts accrued by the Confederacy. Section Five expressly authorizes Congress to enforce the Fourteenth Amendment "by appropriate legislation." The states ratified the Fourteenth Amendment in 1868 in the immediate aftermath of the American Civil War, along with the other Reconstruction Amendments-the Thirteenth and Fifteenth.
