AGAIN -- this is not a backlash against Hispanics, Mexicans, or immigrants.
Those of us who are anti-illegal-immigrant are so for a variety of reasons:
--they have broken the law
--they have violated our national sovereignty
--they are not properly screened for infectious diseases (and yes, we HAVE seen a rise in TB, whooping cough, and other diseases in areas where they cluster)
--they work for under-the-table wages in industries that are now decimated of skilled American workers
But most of all, what this rally showed us was that (a) there is a small vocal assimilaton-rejecting irredentist* faction of the the Mexican nationals and Mexican-Americans here in America and (b) that faction enjoys support from the Mexican government, illegal population, and enough Mexican-Americans to influence the political process.
There is a BIG difference between marching in support of immigrant rights and marching in support of "California was STOLEN from my people and we're taking it back."
*irredentist: One who advocates the recovery of territory culturally or historically related to one's nation but now subject to a foreign government. You know, like the Sudetenland.
