It symbolizes a lessening of one demographic's influence, and an increase of another's, not the end of their worlds. That's what makes entitled outrage so intriguing. It's perfectly understandable, but it's also often disproportionate to the actual 'threat' they seem to perceive.
Intriguing is something that is a matter of intellectual abstraction. For me, there is no abstraction. My opinion is informed by experience. Do the Britons before the Roman conquest still exist? Not culturally...only genetically. Do the Yue of Guangdong before the Han conquest still exist? Not culturally...only their genes remain.
Ask Tecumshsbones if Shawnee culture still exists in a living and vibrant form. Only Shawnee genes still exist combined with others to create something new. Many Indians tried to accommodate the whites by adopting their ways and Christianity. In the process they lost their identity and became shadows of their former selves.
Cultures can fuse to form new cultures. However, that's not happening in California, except for the creation of latin gangbanger culture. That's hardly a model that should be encouraged or accepted.
Canada is a white country. California isn't. It's changed during my lifetime. The state once had a first rate public school K-12 system. Now California ranks 47th out of 50 states in the second rate American public school system.
Impoverished Mexicans and Central Americans came here at the behest of American Big Business, American Leftism, and Mexican political/economic elites. Big Business got slave labor. Leftism got future voters. And Mexican elites exported poverty. They took the jobs of low skilled Americans who wanted and deserved a living wage. Now low skilled Americans are dependent on govt. handouts. They have been transformed. In the process the Americans have become a degraded people. They no longer even adhere to their former creed. They are lost.
