Why is "spanish" looked at as non white?

yes i know alot of spaniards have arab blood but thats besides the point..people in america are retarded they think spanish people are from mexico or puerto rico...although many mexicans etc..are of full spanish descent (from spain)....a girl the other day said to my spanish friend..."ur white stop trying to speak spanish".and he said are you kidding me spanish is a white language...the reason all the indians and blacks and mixed people speak spanish today is because of SPAIN!!!!!!!......americans are so stupid...also people in america consider anyone with olive skin "spanish looking"...because they are referring to the large majority of mixed latinos there are...im italian and im dark skinned and people say you look spanish..and it gets me so mad because i know they aren't referring to spain..there talking about mexican or puerto rican......and yes i know the percentage of spaniards in america is very little thats why everyone thinks mexicans ane puerto ricans are the original spanish speakers..but why are americans so stupid???people just dont care about the world and history..
