"Rabidly Nationalistic" in Mexico

In Mexico City, during a US- Mexico Soccer game, Mexican fans booed the U.S. national anthem, chanted "Osama, Osama", and a group of them who couldn't manage to set a US Flag on fire, had to settle for trampling on it.(I think the manufacturers of American flags are quietly fireproofing them.)

A few points:
bullet The Associated Press described the Mexican fans as "rabidly nationalistic." How come it takes a sports guy to use that kind of language about Mexican nationalism? Why can't the rest of the press figure that out?
bullet The Mexicans aren't chanting "Osama, Osama", because they support radical Islam. They don't. It's just their way of saying "Death to America." See "rabidly nationalistic, "above.
bullet The US team never beats the Mexicans at soccer. That's because America's great athletes are playing real sports.
bullet Do you think those "rabidly nationalistic" guys when they emigrate, (illegally) will become patriots like the late Balint Vazsonyi, or Humberto Fontova? I doubt it. I think you'd be lucky if you got someone as patriotic as Norman Mineta.
bullet Speaking of which, what do you think the chances are of those flag-tramplers heading north and taking the Oath of Allegiance someday? Pretty good, I'd' say. How about them keeping the Oath of Allegiance? Not so good..
