“A northerner, insensitive in some ways and full of self-righteousness could gravely offend a southerner in a second. The northerner would be giving his general opinion, more than likely unasked for, and all unknowing challenging the southerner's every deeply held belief, not to mention, with sundry looks and expressions, suggesting that the southerner was possessed of numerous flaws of character and person. The southerner was bound to see offense in every suggestion, insult in every difference of opinion, and to act upon his stung pride.”
