Explanation:

Whitman's poem "I Hear America Singing", and Hughes' " I, Too, Sing America" have an idea in common - that all people, including black people, are important members of the American society. In his poem, Whitman writes about people of various professions who, despite all the differences between them, feel happy and free in America. Hughes, on the other hand, tries to prove this point through a metaphor: the speaker of the poem (who is a black man) describes himself as a "darker brother" that has to hide in the kitchen when the guests arrive. This man has a right to feel free in his country, but is treated unfairly. The point that both poets try to convey is that freedom should be promised to all people, regardless of their race, profession, or any other factor.
