With equal pleasure I have as often taken notice that Providence has been pleased to give this one connected country to one united people--a people descended from the same ancestors, speaking the same language, professing the same religion, attached to the same principles of government, very similar in their manners and customs, and who, by their joint counsels, arms, and efforts, fighting side by side throughout a long and bloody war, have nobly established general liberty and independence.
-John Jay, Federalist #2
Jay is, of course, citing a putative American unity in a persuasive, even propagandistic manner, to support the cause of Union. But it is telling to note that the diversitarian multiculturalists among contemporary activists do not take the supposed diversity of America as a reason to split, or at least decentralize the Federal government. Perhaps it is because it is easier to turn one central, homogenized government to the multiculturalist cause than fifty recalcitrant state governments.
