How does the concept of intersectionality inform either Anzaldua's or Frances Beal's account of being a woman of color in a sexist and racist society? You might want to relate this to the question of anxieties concerning internal critique of one's culture (or relatedly, to the challenge of solidarity with members of one's race, some of whom are sexist oppressors); or to what aspects of one's oppression are missed in either account on a reductive treatment according to race, class, and/or gender. Are the issues your author describes relevant to contemporary political events, and if so, how?
