“Struggles to coerce uniformity of sentiment in support of some end thought essential to their time and country have been waged by many good, as well as by evil, men. Nationalism is a relatively recent phenomenon, but, at other times and places, the ends have been racial or territorial security, support of a dynasty or regime, and particular plans for saving souls. As first and moderate methods to attain unity have failed, those bent on its accomplishment must resort to an ever-increasing severity. As governmental pressure toward unity becomes greater, so strife becomes more bitter as to whose unity it shall be.”

Though race related issues continue to occupy a significant portion of our political discussion, and though there remain many unresolved racial issues in this nation, we, average Americans, simply do not talk enough with each other about race. It is an issue we have never been at ease with and given our nation’s history this is in some ways understandable. And yet, if we are to make progress in this area we must feel comfortable enough with one another, and tolerant enough of each other, to have frank conversations about the racial matters that continue to divide us.
