Many Americans, including myself, did not grow up with much diversity. But, historically, in America's cities, people could walk out their doors and see the America that Brooklynite Walt Whitman saw and eulogized. From Whitman's I Sing the Body Electric:
The man's body is sacred and the woman's body is sacred,
No matter who it is, it is sacred—is it the meanest one in the
Is it one of the dull-faced immigrants just landed on the wharf?
Each belongs here or anywhere just as much as the well-off, just as
much as you,
Each has his or her place in the procession.
(All is a procession,
The universe is a procession with measured and perfect motion.)
