Why does mccarthy likely mention john service and gustave duran in

Something that McCarthy wanted to do is to prove that Gustave Duran was a communist.

McCarthy actually proved this by narrating when Gustave Duran served in the communist international brigade.

Also, McCarthy claims that John Service friendship with China and communism was the only hope for the United States.

Hope this helps.

explanation:

the answer is:  

he is voicing feelings shared by all humans regardless of race.

in paul laurence dunbar's poem "we wear the mask," he replicates the words mask and we to emphasize how people in general -not just black americans- hide their true feelings. he suggests the masks cover people's faces and eyes, which are the main parts that display their emotions. he also thinks people's pain conceal behind those masks, so that they cannot see reality and nobody is able to see one another's sorrow.
