The original question had to be edited down as there were multiple questions present. I think that the argument here is that El Pachuco is driven to voice the opposite of the Press. Valdez shows the Press to be one of the main instigators in terms of how the White public in Los Angeles viewed the "zoot suiters," and Latinos, in general. In being the embodiment of the defiant Latino, El Pachuco defines himself against the sentiments of the press. The opening of the drama reflects this condition in which El Pachuco slashes through the backdrop of news headlines in the outset of the drama. In slashing through the news headlines, El Pachuco voices an attitude and sentiment that is the opposite of the press.
El Pachuco's empowerment for the Latino voice is opposite of the sentiments of the Press. Acting as the defiant voice of Latino identity that will not waver in the face of hostility that has been fanned in part by the press and media, El Pachuco represents the aspect of Latino identity that will endure and persevere through the imposition of prejudice and racial hostility. When El Pachuco interrupts the narrative to say, "That's exactly what the play needs right now. Two more Mexicans killing each other," it is voicing a sentiment that speaks against the wishes of the Press. Even in the small gesture of telling the boys to sit up straight during their trials, El Pachuco is voicing a sentiment that is decidedly against what the Press says. In his defiant stance and his constant and unwavering support of the Latino voice, El Pachuco repels the voice of the Press, by articulating a condition of empowerment.
