In "Battle Royal" Chapter 1 of Invisible Man, what does the naked blonde lady represent?

In "Battle Royal," the first chapter of
Invisible Man, the narrator has been asked to give a speech only to
find out that he is instead expected to box on stage.  Before the boxing matches begin,
the crowd gets quite drunk and a naked blonde lady is paraded across the stage for the
whole crowd to see.  The members of the crowd are primarily white male spectators and
the boys who will box are black youth.  Amid this scene, the naked blonde lady is a
symbol for the stereotypical notion that white women are unattainable yet desired by
black men.  So she is put on display for the spectator crowd to suggest their ownership
of her sexuality.  Further, the boxing match is a scene that shows the power of the
crowd and the organizers over the young black men, and so too does this power extend to
women.  As a result, the entire scene is a complete backlash against the supposed values
of the American system and what the narrator thought he would speaking about when
agreeing to come to the event.
