Why don't Americans treat Latinos as white people?

This is caused by history. Americans have always rejected Hispanics, because in their view, South America is as high-risk as the United States, and the problems brought by illegal immigrants to American society have been plaguing the United States. In addition, after hundreds of years of evolution, most Latin Americans have become hybrids. True whites, like African-Americans, are actually 95% mixed-race, including Obama and NBA stars. Therefore, Americans have never regarded Latin Americans as white people, and have always regarded Latin Americans as colored people.
