No, I believe I am correct. Hispanic refers to people of Spanish descent in the New World, not to Spaniards. And by the way, there are very few “Castillian Cubans”. The vast majority of Spanish immigration to Cuba was from Galicia, the Basque region, Catalonia, the Canary Islands and Asturias.
Very few, just the ruling class, yes. Same people that run Mexico and New Mexico.
