Mexicans are rather unusual to find running loose in Fairfax County. Our Hispanics come from different countries. No doubt these people are as confused as anyone ~ thee is, after all, no friendly Mexican community here to welcome them and hide them out!
Which Fairfax County do you live in? I visit often, and agree that there are a lot of Salvadorans and South Americans, but Mexican nationals probably outnumber them 2:1(in Arlington, as well)...
Adding to that, the number of asians and middle easterners is increasing exponentially. There are lots of Mosques being built for our ROP'ers, and the authorities seem to be encouraging them.
Remember one thing, that our friend Rushbo always mentions..."follow the money".
Gum't types make their money by making gum't bigger. Schools are loaded with gum't employees (union members). Gum't rewards schools with larger enrollments, with larger disbursements of our money... The same applies to Social Services, and most other gum't agencies... They gotta spend all they get this year, so they can get more next year!
