There are a lot of confused peope around here...
First, there are several meanings to the term hispanic, but the one you're using is the american one, that is, Hispanic is someone whose family is from one of the spanish speaking countries of Central and South America. That's it.
No one in Europe uses the term "hispanic", not even in Spain.
As for the portuguese, for some mysterious reason many americans seem to think they have some relation to the spanish or to Spain. It's simply not true.
Portugal is the oldest country in Europe and one of the oldest in the world.
It was created in 1143, in a time when what was to become "Spain" was 6 different kingdoms all rivals to one another not even dreaming they would become one nation. Spain gained it's current shape and size in 1492, so do the math, Portugal is OLDER than Spain almost 450 years.
One other thing, Portugal did not "come from Brazil", that's like saying England came from the USA, Brazil is a former portuguese colony, like many other around the world, the african nations of Cape Verde, Guinea-Bissau, St. Tome and Principe, Angola and Mozambique. The indian cities of Damao, Diu and Goa. The chinese city of Macau. And the island of Timor near Indonesia, once part of the first global empire of the world, the portuguese empire, far wider and more important than the spanish one, it reached from Lisbon to Brazil to Africa to India to China and to Japan, where the portuguese were the first europeans ever to arrive in 1543, founding the city of Nagasaki and introducing the firearm to the japanese. To this day there are 250 words in the japanese language that comes from the portuguese, including "arigato" deriving from the portuguese word for "thank you", "Obrigado"...
So please, do not use the term hispanic, your family is PORTUGUESE, therefore european. For another mysterious reason many americans seem to think the spanish or portuguese can be named "latinos" like they were some kind of separate race from the other europeans. They are not, Europe is a multicultural entity, there are europeans blond with blue eyes and dark skinned with brown eyes, they're all european, only ones are northern european and others southern european.
So be very proud of your portuguese origins.
