Who is the narrator addressing in the first seven stanzas of "Still I Rise"?

The speaker is addressing her remarks to those white racists and bigots who've kept down black people for centuries. Such individuals have used a number of strategies to this end, from willfully distorting history to using hateful, offensive words designed to wound and hurt.

The speaker's response to centuries of oppression is one of defiance; she's not going to tolerate the continued denigration of her race. On the contrary, she's going to affirm her identity as an African American woman in the face of racial hatred, making her oppressor aware in no uncertain terms that, whatever he says and whatever he does, she will remain strong. She refuses to be broken by oppression, to go around with bowed head and lowered eyes. Instead, she'll rise and keep on rising.

Who is the poem "Still I Rise" addressed to?

To answer in today's parlance, "this one goes out to all the haters."

In essence, Maya Angelou's defiant, triumphant "Still I Rise" is addressed to everyone attempting to keep the speaker down. Written from the perspective of an African American woman, arguably one of the most oppressed classes of people in the USA, the "you" in the poem is the dominant culture that "want[s] to see [her] broken."

The poem is deeply rooted in history, referencing slavery and the speaker's ancestors. In the face of systematic oppression and historical abuse, the speaker celebrates her own blackness, throwing her pride in the face of the "you" that would try to keep her down. In stanza 7, which begins, "Does my sexiness offend you?" the speaker also flaunts her feminine sexuality, refusing to be embarrassed or policed by societal expectations.
