Here's a David Goldman (aka, Spengler) essay on the topic:
The Confederate battle flag is what makes America stupid: Spengler

in part, Goldman writes:
As the New York Times reports this morning, not a single Republican presidential candidate has the courage to tell South Carolina to stop flying the Confederate battle flag from its state capitol. It is a bit late for that, to be sure; public display of any kind of the symbol of the slaveholders’ rebellion should have been banned after the Union victory in 1865. Removing the Confederate flag from the grounds of South Carolina’s seat of government has become an African-American cause in the wake of last week’s Charleston church massacre. It may be incommensurate with the crime, but black Americans are entirely justified in their rancor against official sanction of a symbol of slavery.
On moral grounds I sympathize with the African-American view, but there is an even more urgent reason to rip down the Confederate flag. Our refusal to look squarely at the evil character of the American Confederacy turned us into idiots. It may be a bit late to remedy this national lapse in mental capacity, but one has to start somewhere.
America never recovered from its Civil War, which killed nearly a million combatants on both sides. The Union won on the battlefield but conceded a cultural victory of sorts to the defeated South, spinning a myth of Southern gallantry in a lost cause. This myth dominated the popular culture from D.W.Griffiths’ 1916 epic “Birth of a Nation” (which celebrates the rise of the Klu Klux Klan).

I'm not sure that the problem is the difference in views, but the idea that violence (force) toward opposing views is the way to reconcile the difference.
