It's not real californians who have created this "world", but transplants from other parts of the country and from abroad. In 2000 CA voters voted by a margin of 61%+ in favor of defining a marriage as between one man and one woman. In the intervening years we've had an influx of out-of-staters from other liberal areas of the country, and that is affecting our state's politics.
Net growth in California has been negative among U.S. citizens, from what I've read. It is possible, though that New Yorkers are almost displacing native/long-time Californians, who are leaving in droves.
