You must be an illiterate. However, let me just spell it out for you. Why can't you explain what a "Latino," is? Is this supposed to be a nationality? or an ethnic group? or an easy catch-all word? Yeah, if someone defies a stereotype this upsets you?
What? machismo is supposed to be the antithesis to acceptance? In other words, by labeling someone as a machismo person this is supposed to make them wicked and less tolerable? 
The story wants to make machismo and Latino the butt of intolerance and hate. However, it only weakens a one-source story, so common to lazy writers and inept editors.
