Explanation:

In his poem "I, Too", Hughes explores the theme of racial discrimination, which was largely present in the society at the beginning of the 20th century.

The speaker of the poem claims his right to "sing America" - to be an equal part of the American society. He wants to point out that he is allowed to have patriotic feelings towards America, despite the fact that he is black.
