Proponents of the Living Constitution suggest that a dynamic view of civil liberties is vital to the continuing effectiveness of the constitutional scheme. It is now seen as unacceptable to suggest that married women or descendants of slaves are not entitled to liberty or equal protection with regard to coverture laws, slavery laws, and their legacy as they were not expressly seen as free from such by those who ratified the Constitution, and advocates of the Living Constitution believe that the framers intended or certainly demanded their 18th-century practices to be regarded as the permanent standard for those ideals.
