This is just more "wisdom" from a dilletante living comfortably a few thousand miles from California. East Coast kids know all about Mexico, they've eaten at Taco Bell, after all, and some of them have actually heard Spanish spoken. When they're old enough to drive they may even come out to the barrio and hang with the homies, knock back a few cervezas, and tag the neighborhood.
Hmmm, that explains why I just got the ad hominem attack. You know I live in LA.
Your reasoning is weak.
