Looking back at the some of the posts in this thread, I noticed the American flag was mentioned...and some apparently see it as hypocrisy that Confederate flags are associated with racism while the American flag is not.
For those people I suggest reading the speech given by Confederate Vice President Alexander Stephens in 1861, where he lays out the differences between his new 'nation' and the United States they had seceded from.
The new constitution has put at rest, forever, all the agitating questions relating to our peculiar institution -- African slavery as it exists amongst us -- the proper status of the n3gro in our form of civilization. This was the immediate cause of the late rupture and present revolution. Jefferson in his forecast, had anticipated this, as the "rock upon which the old Union would split." He was right. What was conjecture with him, is now a realized fact. But whether he fully comprehended the great truth upon which that rock stood and stands, may be doubted. The prevailing ideas entertained by him and most of the leading statesmen at the time of the formation of the old constitution, were that the enslavement of the African was in violation of the laws of nature; that it was wrong in principle, socially, morally, and politically. It was an evil they knew not well how to deal with, but the general opinion of the men of that day was that, somehow or other in the order of Providence, the institution would be evanescent and pass away. This idea, though not incorporated in the constitution, was the prevailing idea at that time. The constitution, it is true, secured every essential guarantee to the institution while it should last, and hence no argument can be justly urged against the constitutional guarantees thus secured, because of the common sentiment of the day. Those ideas, however, were fundamentally wrong. They rested upon the assumption of the equality of races. This was an error. It was a sandy foundation, and the government built upon it fell when the "storm came and the wind blew."
Our new government is founded upon exactly the opposite idea; its foundations are laid, its corner- stone rests upon the great truth, that the n3gro is not equal to the white man; that slavery -- subordination to the superior race -- is his natural and normal condition. [Applause.] This, our new government, is the first, in the history of the world, based upon this great physical, philosophical, and moral truth. This truth has been slow in the process of its development, like all other truths in the various departments of science. It has been so even amongst us. Many who hear me, perhaps, can recollect well, that this truth was not generally admitted, even within their day. The errors of the past generation still clung to many as late as twenty years ago. Those at the North, who still cling to these errors, with a zeal above knowledge, we justly denominate fanatics. All fanaticism springs from an aberration of the mind -- from a defect in reasoning. It is a species of insanity. One of the most striking characteristics of insanity, in many instances, is forming correct conclusions from fancied or erroneous premises; so with the anti-slavery fanatics; their conclusions are right if their premises were. They assume that the n3gro is equal, and hence conclude that he is entitled to equal privileges and rights with the white man. If their premises were correct, their conclusions would be logical and just -- but their premise being wrong, their whole argument fails. I recollect once of having heard a gentleman from one of the northern States, of great power and ability, announce in the House of Representatives, with imposing effect, that we of the South would be compelled, ultimately, to yield upon this subject of slavery, that it was as impossible to war successfully against a principle in politics, as it was in physics or mechanics. That the principle would ultimately prevail. That we, in maintaining slavery as it exists with us, were warring against a principle, a principle founded in nature, the principle of the equality of men. The reply I made to him was, that upon his own grounds, we should, ultimately, succeed, and that he and his associates, in this crusade against our institutions, would ultimately fail. The truth announced, that it was as impossible to war successfully against a principle in politics as it was in physics and mechanics, I admitted; but told him that it was he, and those acting with him, who were warring against a principle. They were attempting to make things equal which the Creator had made unequal.
Cornerstone Speech
There is no question that racism existed in the United States long before the Civil War, and continued to exist long after it. The United States however was not explicitly founded on a doctrine of white supremacy, unlike the Confederacy, and in many ways it can be argued that America's failings were in not living up to the country's highest ideals. The Declaration of Independence declared, "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness." The Confederates rejected this, and instead attempted to found a nation based on the doctrine that all men are not created equal.
The Confederacy was one of the more vile governments in human history, and it richly earned its place in history's garbage heap. It would be fitting if its flags followed suit.
