in the precicely defined meaning of hispanic,you wouldn't meet the definition. as the word hispanic has it's root in the name hispanola,which in very rough translation equates with "of spain,or new spain" there are no parts in that word that refers to portugal. but in the loose vernacular used today around the word hispanic,many people of latin descent,if asked,would probably say yes,that you're hispanic. I suppose you might skirt the issue by saying that you're latino. then again,I could be all wrong. the one thing I'm positive about is that; there is one race,yes,the human race,but there are three subgroups. and every human falls into one or more of the three. those groups are the negroid,the mongoloid,and the caucasoid. all of the rest, in a sense,is extranious.
Hispanic refers to a Spanish-speaking person, especially one of Latin American descent. You cannot possibly be considered Hispanic since you are of Portuguese and Asian descent. People of Portuguese descent typically speak Portuguese, not Spanish.
