The servile quality of this white-influenced stereotype is further reinforced by the idea of Mexicans being 'sold' like used car models -- this shows how dehumanized Mexican-Americans are in white society, as they are treated like laborers, not as individuated human beings, and how the concept of a type of Mexican is indeed a 'model' -- another word for a stereotype. Johnny embodies the fears of white society -- that Latino men are more sexualized than white men, and more violent. The Mexican-American is a Republican fantasy, a man who can eat Mexican food at a political meeting for show, but prefers sipping martinis.

They are forced to look behind the stereotypes after watching the play and see humanity behind the dehumanized 'model.' By watching the play the viewer his forced to confront his or her own assumptions, and to challenge the models in his own mind, rather than pretend such stereotypes do not exist.
