what is the point of this splintered whole? what is the point of a nation in which arab
cabbies chauffeur jewish passengers through the streets of new york - and in which jewish cabbies
chauffeur arab passengers, too, and yet speak in a theory of hatred, one for the other? what is the
point of a nation in which one part seems to be always on the verge of fisticuffs with another, black
and whites, gays and straights, left and right, pole and chinese, and puerto rican and slovenian?
other countries with such divisions have in fact divided into new nations with new names, but not
this one, impossibly interwoven even in its hostilities.
