Why does James call "mommy.... a flying complication of competing interests and conflicts"?

From the text:

Doctors found squamous cell cancer in a small mole they removed from Ma’s face, a condition caused by too much exposure to the sun. Ironically, it’s a condition that affects mostly white people. To the very end, Mommy is a flying compilation of competing interests and conflicts, a black woman in white skin, with black children and a white woman’s physical problem.
