We have reached the point where all the Confederate soldiers, their kids, and most of their grandkids are dead. So you aren’t going to personally offend anyone by badmouthing the CSA. If you get upset by someone saying your great-great-grandfather was on the wrong side of the war, you need to let it go.
The issues are not dead and gone.
Dwight L. Dumond, a northern man (Michigan native, studied and taught at the University of Michigan) writing in a period when historians would honestly state the position of even those with whom they disagreed defined the issue this way:
The state-rights men considered the federal government an agent of the sovereign states, entrusted with certain carefully defined powers, for the performance of specific duties. State governments, they maintained, did not derive any power whatsoever from the Constitution or the federal government; on the contrary, whatever powers the latter possesses were bestowed upon it by the states through the Constitution. Its powers being derivative, the state which delegated them might take them away. Whatever powers had not been delegated to the federal government nor prohibited the states had been reserved to the respective states. The fact that a division of powers had been made confirmed the intention of limitations, and implied a power capable of enforcing restrictions. The question was, where did this power of determining the extent of limitations and reserved powers reside? Webster and the federal school said that in all suits in law and equity the Supreme Court was the final judge, and that in cases not capable of being argued before that tribunal Congress must judge of, and finally interpret, the powers of the federal government. Calhoun, Hayne, and the state-rights school held this doctrine to be a presumption utterly unwarranted either by interpretation of the Constitution itself or the circumstances of its inception. They regarded the Constitution as an instrument of union between states which had never surrendered their sovereignty nor agreed to unlimited submission to the government created by the compact. The states, and not the government so created, were the final judges of the extent of their reserved powers. In case the federal government arrogated authority beyond the limits of the delegation or encroached upon the reservations, each state had the right to determine for itself the nature and extent of remedial measures.
They maintained that it is the nature of all delegated power to increase; that, if the general government were invested with the right to determine the limits of its own powers and enforce its decisions, the Constitution would no longer act as a shield against encroachments upon the vested rights of the people and the independence of the states; that, under the theory of the federal school, there was no real, positive division of powers, since Congress or the Supreme Court, or the two operating harmoniously, might enlarge upon the delegated powers by usurpations; that, therefore, in the last analysis, a government which is the sole judge of the limits of its own powers becomes an absolutism. They contended that the principal justification for the creation of a government by a free people is to afford protection for minorities against the despotism of majorities in cases of internal dissension and sectional disputes; and that, unless some protective power be provided as a restraint upon the will of the many as against the few, the latter, however justifiable their position and sacred their menaced rights, must yield to the stronger party. If, therefore, the majority were invested with definitive rights and unlimited executive powers, the rights of the minority must, of necessity, become subject to the selfish pleasure and unrestrained ambitions of a legislative majority. The Southerners insisted that there must be a self-protecting power in the hands of the minority. Limitations placed upon the power of the federal government by states would no longer restrain, and powers which had never been delegated by the states would be usurped, unless the ultimate source of authority in all cases of dispute rested with the states for whose benefit limitations had been imposed and reservations had been made. It was not in the nature of things for majorities to search constitutions to determine in what respects the rights of minorities were to be observed. These were never safe if protest and remonstrance were the only recourses available. State interposition and secession were, therefore, the only safe and effective measures of resistance, and the right of a state to exercise them was indisputable. They were effective remedies, too long fallen into disuse, in the opinion of the state-rights men, but not completely forgotten nor in any sense discarded.

Those are issues that are still with us.
Most Americans are not even aware that an alternative exists to the Massachusetts School (the Federal government does not wield sovereign powers delegated by the peoples of the states, but is
itself sovereign, and the sole judge of the limits of its own powers). The Virginia School (stated above by Dumond) presents an alternative interpretation. Having read the texts of
Elliot's Debates (the records of the state conventions that debated the meaning of the Constitution and did the actual delegating of powers to their creation, the general government), is the
only interpretation which can be supported by the ratification debates. Nobody,
not a single delegate in 1787-1790 argued that the Constitution should be ratified because the general government will be sovereign and, if any state that attempts to leave the Union, they will be committing treason and the general government will be justified in invading that state, killing its citizens, and overthrowing its elected government. Despite this, four-score and five years later, Abraham Lincoln would make
exactly this argument.
