White Latinos are quite common, as the “Castillano” bloodline is alive and well in Mexico and other Latin American nations. It is important to understand the foundation of white racism that grows from Mexico City to feed the same forms in LA. It is important to note that most upper class Mexicans consider themselves to be “Spanish” before Mexican, separating themselves from the masses.
Black Latinos are common as well; "Mulattos" are rather low on the social scale though, in fact below the "Mestizo" or indigenous populations of Latin America.
The oligarchy of Mexico is extreme and has left its people with great temptation to leave. One can hardly blame the immigrants themselves, whether legal or not. “Coyotes” , those who assist illegal immigrants in their border crossing, are mercenaries who will take poor people’s money, and stuff them into various spaces as cargo to be smuggled, many of whom die in passage, much like black slaves in ships in early US History.
As for conspiracies, that implies a plan. It would require affirmative activity. In this case, there is a deadly apathy on the part of the larger part of whites in LA as to the plight of Black and Brown. We typically find a highly insulated white community tucked away behind gates, driving past the neighborhoods on superhighways which allow them to simply ignore poor people.
There is no political will among whites to solve the problems as those who can afford it, put their kids in private schools or rich sub-municipalities like Beverly Hills, further insulating them from concern, i.e. "Valley Girls" and the like.
The only exposure they have to the inner cities is through the movies, just like the rest of America, which is replete with racial stereotypes at best and ignorance at least.
Many books have been written on these subjects and an article hardly does justice, but to stimulate further research.
It should be noted that this form of racism in the form of apathy, is pervasive in LA, San Francisco, Houston and Atlanta; basically anywhere one finds high black and Latino populations. Sadly, what happens in LA is an indicator of what will and has already happened in the other cities. As LA has, for many years now, seen movements to secede from the city, so have cities like Atlanta experienced powerful, well funded movements to leave the inner cities without funding from their suburban counterparts.
In LA, the San Fernando Valley has attempted such secession and in Atlanta, the wealthy northern suburbs of N. Fulton Co. have recently attempted to leave, to form their own county. It is yet to be seen if the state of Georgia, long led by rural racists, will allow this abandonment. In LA, it seems to be under control at the moment, but LA has already suffered disenfranchisement in the form of enclaves like the cities of Beverly Hills, Santa Monica and Malibu.
Meanwhile, the violent intrusion of Latino gangs into traditionally black neighborhoods in South Central LA, Compton and surrounding areas, has led to horrific and much ignored suffering and death.
One is left with the question, if blacks have to flee Compton for fear of their lives, where can they live?
