Mexicans can be Caucasian (Spanish) or Mongoloid depending on how much American Indian blood the Mexican person has.
My Wife’s Mother who was born in Mexico City is Caucasian.
She and her Daughters resent anyone using the word “Latina” when describing them.
Since my Wife’s Father is from Oklahoma, I could call her an Okietina and see what happens. #;^)
What people do not understand is there is a Caste System in Mexico, the Whites and the Little Brown People.
The Whites stay put or Emigrate Legally and the Little Brown People come here Illegally for the most part.
