I'm probably wrong, but from what i understand, people from spain are spanish, and not hispanic..
The places that the conquistadors occupied and or conquered where there was a mixing of the blood produced hispanics.
This spanish kid i knew in high school said sangre azul, which meant something like blue blood, or pure blood, and sangre de conquistadors, which means blood of the conquistadors, or i think conquerors.
I'm not spanish or hispanic, i'm just repeating what i was told a while ago.
