“As one might expect, the gunman’s fondness for Confederate heritage has become a focus of discussion. We’ve had people calling for the banning of Confederate flags as symbols of hate while certain defenders of Confederate heritage, sometimes after offering perfunctory statements of regret, rush to disassociate their cause from this mass murder or to offer other explanations for the gunman’s behavior. That’s to be expected, and it is to be regretted. We’ve had far too much discussion of the Confederate flag, both by people who hate it and people who love it, that trivialize the whole matter by turning it into a screaming match between extremes. Thoughtful commentary flounders in such environments, precisely because both sides will assail it. It's Sunday. If you haven’t already done so, think about the victims and their families and friends. Pray for those who have suffered. And think before you respond.”

2015, Eulogy for the Honorable Reverend Clementa Pinckney (June 2015)
Context: For too long, we were blind to the pain that the Confederate flag stirred in too many of our citizens. It’s true, a flag did not cause these murders. But as people from all walks of life, Republicans and Democrats, now acknowledge -- including Governor Haley, whose recent eloquence on the subject is worthy of praise as we all have to acknowledge, the flag has always represented more than just ancestral pride. For many, black and white, that flag was a reminder of systemic oppression and racial subjugation. We see that now. Removing the flag from this state’s capitol would not be an act of political correctness; it would not be an insult to the valor of Confederate soldiers. It would simply be an acknowledgment that the cause for which they fought -- the cause of slavery -- was wrong -- the imposition of Jim Crow after the Civil War, the resistance to civil rights for all people was wrong. It would be one step in an honest accounting of America’s history; a modest but meaningful balm for so many unhealed wounds. It would be an expression of the amazing changes that have transformed this state and this country for the better, because of the work of so many people of goodwill, people of all races striving to form a more perfect union. By taking down that flag, we express God’s grace.

Context: These soldiers were using the word slavery in the same way that Americans in 1776 had used it to describe their subordination to Britain. Unlike many slaveholders in the age of Thomas Jefferson, Confederate soldiers from slaveholding families expressed no feelings of embarrassment or inconsistency in fighting for their own liberty while holding other people in slavery. Indeed, white supremacy and the right of property in slaves were at the core of the ideology for which Confederate soldiers fought.

Context: It would be wrong, however, to assume that Confederate soldiers were constantly preoccupied with this matter. In fact, only 20 percent of the sample of 429 Southern soldiers explicitly voiced proslavery convictions in their letters or diaries. As one might expect, a much higher percentage of soldiers from slaveholding families than from nonslaveholding families expressed such a purpose: 33 percent, compared with 12 percent. Ironically, the proportion of Union soldiers who wrote about the slavery question was greater, as the next chapter will show. There is a ready explanation for this apparent paradox. Emancipation was a salient issue for Union soldiers because it was controversial. Slavery was less salient for most Confederate soldiers because it was not controversial. They took slavery for granted as one of the Southern 'rights' and institutions for which they fought, and did not feel compelled to discuss it. Although only 20 percent of the soldiers avowed explicit proslavery purposes in their letters and diaries, none at all dissented from that view. But even those who owned slaves and fought consciously to defend the institution preferred to discourse upon liberty, rights, and the horrors of subjugation.
