What is Quindlen's claim in the following paragraph? Explain in your own words. This is a nation founded on a conundrum, what Mario Cuomo has characterized as “community added to individualism.” These two are our defining ideals; they are also in constant conflict. Historians today bemoan the ascendancy of a kind of prideful apartheid in America, saying that the clinging to ethnicity, in background and custom, has undermined the concept of unity. These historians must have forgotten the past, or have gilded it. The New York of my children is no more Balkanized, probably less so, than the Philadelphia of my father, in which Jewish boys would walk several blocks out of their way to avoid the Irish divide of Chester Avenue. (I was the product of a mixed marriage, across barely bridgeable lines: an Italian girl, an Irish boy. How quaint it seems now, how incendiary then.) The Brooklyn of Francie Nolan’s famous tree, the Newark of which Portnoy complained, even the uninflected WASP suburbs of Cheever’s characters: they are ghettos, pure and simple.
