What metaphors are used in Red Roses for Me by Sean O'Casey?

Much of the play is a metaphor for religion. First, there is the heated dispute between Catholics and Protestants. Unlike the labor dispute, however, members of the two groups do associate with each other. In fact, the Breydons' apartment is located in a tenement building that houses both Protestants and Catholics, a situation that would never happen between working-class and wealthy people. These two religious groups interact with each other throughout the play. In many situations, these groups argue, most notably when Brennan, a devout Protestant, argues with Roory, a devout Catholic. Brennan tells Roory, "God save th' King, an' tae hull with th' Pope!" while Roory counters with "You damned bigot—to hell with th' King, an' God save th' Pope!"
