Are people whose ancestors are all from Spain considered "Latino?"

There is still debate about that.

By many accounts Spaniards who never made it to Latin America are white Europeans.

People from Argentina or Peru all of whose ancestors come from Spain or Italy are considered Latino in the United States, but white in South America.

There is also debate about whether Brazilians qualify as Hispanic or Latino.

There are about 200 million people in Brazil...about 100 million self-identify as Black.
(There are more Blacks in Brazil than any other country outside Africa)
