Explain why Montag decides to read "Dover Beach" to Mildred's friends. What is its message?

Montag reads the poem "Dover Beach" . The poem is symbolic of their society. It becomes a sad commentary about their own society. It decries that faith being once so full was now "retreating, to the breath of the night wind" . It reflects on society having "neither joy nor love nor light" anymore." This of course is a valid representation of their own society.
