Emigration and immigration.
Serbs living in Kosovo have been intimidated and threatened (and murdered) for decades by ethnic Albanians. In response, the Serbs left Kosovo for safer areas by the thousands. A majority of Kosovars are ethnic Albanian and this majority has only increased over the years.
I am not choosing sides. Whether the Serbs or the Kosovors are right or wrong in this respect is not an issue in this discussion. But this is the result when an ethnic majority decides that they no longer want to be part of an already established nation.
And this is what can happen in California, Arizona and New Mexico if our slack brained politicians don't get their collective heads out of their asses and insist on maintaining American sovereign control over our southern border.
We have allowed political correctness to dictate a completely inappropriate response to a literal invasion from another country, Mexico. Mexican nationals (see La Raza and Movimiento Estudiantil Chicano de Aztlan or MEChA) have already established a presense that insists that California must be returned to its former masters - as specified in the following:
"Chicano is our identity; it defines who we are as people. It rejects the notion that we...should assimilate into the Anglo-American melting pot...Aztlan was the legendary homeland of the Aztecas ... It became synonymous with the vast territories of the Southwest, brutally stolen from a Mexican people marginalized and betrayed by the hostile custodians of the Manifest Destiny." (Statement on University of Oregon MEChA Website, Jan. 3, 2006)
We are already experiencing an eruption of Kosovo style intimidation in our border states. It will only get worse as our politicians seek to appease Mexican radicals.
"In the spirit of a new people that is conscious not only of its proud historical heritage but also of the brutal gringo invasion of our territories, we, the Chicano inhabitants and civilizers of the northern land of Aztlan from whence came our forefathers, reclaiming the land of their birth and consecrating the determination of our people of the sun, declare that the call of our blood is our power, our responsibility, and our inevitable destiny. ... Aztlan belongs to those who plant the seeds, water the fields, and gather the crops and not to the foreign Europeans. ... We are a bronze people with a bronze culture. Before the world, before all of North America, before all our brothers in the bronze continent, we are a nation, we are a union of free pueblos, we are Aztlan. For La Raza todo. Fuera de La Raza nada."
