I grew up Spanish in Asia and Europe, and never heard that Spain was considered non-white. Not, that is, until I came to the US.
The US is very confused on the matter because nearly all the Spanish speakers they have ever seen are from the former colonies of our empire. There have been very few direct immigrants from Spain to the US, historically. Had there been as many immigrants from Spain as there were from Italy it would have been something else.
I think you are right, buwaya.
My parents came from Italy,right next door to Spain and were not considered non white.
That seems very unfair.
Welcome to America. Remember though, Italians did not have an easy time of assimilating, but they worked at it very hard.
