How does Angelou's comment about the liberal woman from Texas identify the immediate audience for her essay?

By commenting that the "WHITE woman from Texas [. . . who was] a liberal" asked about her hometown, Maya Angelou presents us with the realization that the essay/ short story's intended audience is those white people who put themselves superior to the 'blacks' and the apparent disparity between the two.

Explanation:

Maya Angelou's short narrative story "My Name Is Margaret" is about the author's experience while staying with the Cullinan family. The short story revolves around her experience living as a black woman amidst the prejudice prevalent under racism.

On the very first lines of the first paragraph of the section, Maya Angelou started her story with the lines "RECENTLY A WHITE woman from Texas, who would quickly describe herself as a liberal, asked me about my hometown." With the emphasis on the words "RECENTLY A WHITE", she brings the focus on the 'race' of the woman. Added to that, she pointed out that she was "a liberal", from Texas. Considering the America of her time, it can be immediately inferred that this southern state of America will be under prejudicial discrimination against the blacks, thus confirming the intended audience as the white people who think themselves superior to the blacks while the blacks 'involuntarily' identify themselves as the lower race.
