I live in National City, hard by the city of San Diego, Mexican population 67%. I hear Mexicans (maybe they are “Americans”) conversing in Spanish every day I venture out. This includes children with parents and employees speaking with each other at Walmart and other stores. Californians will be fortunate to be in a bilingual state in the future. There is a good chance that English will be supplanted by Spanish as the major language, eventually.
California is already a colony of Mexico.
That’s why your state government protects Mexican citizens from US laws, but won’t protect US citizens from Mexican citizens.
