Why should we distinguish between Hispanics and white blacks in America? Aren't Spaniards also white? Do Spaniards look different from other Europeans?

Spaniards in the United States are automatically divided into white Europeans, former Spanish colonies (collectively referred to as Hispanics) and prosperous Spanish colonies, including Europe (Belgium, Netherlands, Italy, Luxembourg, Portugal, etc.). ), North America, South America, North Africa. So all of South America was once a Spanish colony. During the colonial period, about 20% of mixed-race people in South America (Spanish whites and Indian mixed-race people) spoke Spanish. Since the independence of South American countries, whites have basically returned to China, leaving only a few whites at the top of society. Some hybrids look more white. Most South American lineages are mainly Indians and 20% mixed-race. And these hybrids are classified as Hispanic in the United States.
