I am not sure why it is so difficult for Mexican immigrants to integrate and assimilate with American culture now that they or some of their family are American citizens. Sure you are proud of your ancestry, almost every immigrant is proud of their ancestry. But most immigrants understand that the most important thing you can do is assimilate into American society, speak, read, and write English, and stop the "California is really Mexican territory" nonsense because that is un-American. It's American territory won in a war as in any war between 2 nations. Virtually every piece of land on Earth has been owned by more than one country throughout it's history. The last country owning the land claims sovereignty. There is no "do over" in war, unless you start another war. Which is the long term goal of La Raza (The Race), the racist organization that wants to return California to Mexico. If returning land to the rightful owner, doesn't that mean Spain gets California?
