What metaphors are used in Black Is My Favorite Color by Bernard Malamud?

"Every man is a Jew though he may not know it." In an interview with the Fields appearing in the same collection, Malamud offered a sobering clarification of this statement, calling it "a metaphoric way of indicating how history, sooner or later, treats all men." The shadow of the Holocaust hangs heavy over these words, as indeed it does over all of Malamud's work.
