Don't matter which language a Californianer speak, forgieners will allways say it's wrong.Same problem with us englishers, we have to listen to united stater or britishers insult the way we speak also. Yous all should accept that Californianers talk our own way, and it's no less valid then the way yous talk.
Being from Virginia myself, Californian dialect always sounded odd. The media over here has a connotation of a bunch of beach-addicted young people with no sense of authority. But then again, this is the USA we're talking about; very dour by the world's standards.
