There are white mexicans.
I don't see how this is a problem.
This the thing fools don't realize. Mexicans ain't a racial group. I worked in mexico for years. There are mexicans who are gingers with red hair. Mexicans with blond hair and blue eyes. Mexicans of african descent with skin darker than mine. Mexicans that are of jewish heritage. Mexicans that are of middle eastern heritage and mexicans that are asian.
