It's because of people like you posthuman that 68.8% percent of Mexican immigrants to the U.S. state that Mexico comes first in questions of loyalty (see Zogby poll commissioned by the Center for Immigration Studies link below).

Furthermore, even though the United States paid handsomely for the land it acquired and Mexican President Santa Anna was only too happy to oblige, an earlier June 2002 Zogby International Poll showed that 58 percent of Mexicans in the U.S. polled agreed that the "territory of the United States Southwest belongs to Mexico." That's "belongs to Mexico" as in the present and the future. It doesn't take a rocket scientist to see the deep and serious enculturation problem with that statistic.
The Mexico-first attitude dominating much of the Hispanic youth in the U.S. and the gangs they form has taken years of codependence to cultivate, aided primarily by liberals such as yourself and the deliberate misinformation from groups like Movimiento Estudiantil Chicano de Aztlan (MEChA) which explicitly tells them to reject the notion that Hispanics should assimilate into the American melting pot.
Miguel Perez, President of Cal-State Northridge's MEChA chapter,
said, "The ultimate ideology is the liberation of Aztlan. Once Aztlan is established, ethnic cleansing would commence: Non-Chicanos would have to be expelled and opposition groups would be quashed because you have to keep power."

It's in this context that you've then attempted to minimize the threat to the nation and loyal American kids as occurred in Morgan Hill in which groups of Hispanics run around high school campuses carrying Mexican flags threatening to violently assault patriotic students for wearing t-shirts with the American flag.
And let me tell you that it was NOT this pronounced before. As a kid, I used to box and wrestle at the Boys Club with Hispanics (e.g. some prefer Latino which is fine) who were LOYAL AMERICANS that proudly flew the American flag. I served with them in the U.S. military. The older Hispanics I know aren't haters but were hard workers who made a life here. They either fly the U.S. flag or both flags. I LIVE in Southern California.
This rabid anti-American, racist, pro-violent, gang-oriented, La Raza ("all for La Raza none for anyone else") promotion of Reconquista and ethnic cleansing springing from Hispanic militant hate groups has only been around since the 1960s and though its members were always bad apples didn't gain the traction with respect to numbers that it has today among the youth until fairly recently.
The problem has arisen primarily due to the systemic breakdown of the immigration system that was designed to adequately enculturate incoming immigrants. Waiving the amnesty wand over millions of people that remain unenculturated to the point of hating you and the nation giving them "free" amnesty doesn't solve anything. In fact, it makes things worse because it makes it possible for them to stay and tear down your culture and hurt you.
We need to bring discipline to bear in a way that favors those loyal to the United States and begin
finally enculturating all of these misinformed anti-American Hispanic anchors and illegals that are roaming around claiming their U.S. public school campuses for Mexico and threatening American kids.
