I have spent a few minutes trying to find a link but I am unable to, so this is from memory. About 20 years ago Hispanics filed suit against the Mountain View, Ca. Fire Department. they contended that the MVFD was discriminating against Hispanics by hiring persons of Spanish origin.
I’m not Hispanic and so cannot say who is right but there does seem to be a distinction between “Hispanics” named Gutierrez and Spanish of the same surname.

My point: It is very sad that we need to make such distinctions among Americans but that is the country we live in.
