From which shade of color do you consider someone black or white? If color defines a race, surely white korean people are the same race as Irish and German people and most malaysians are blacks right? What about people born from parents with way different skin tones or any other characteristic you can think of? And why aren't blond haired people not considered a different race than white people with brown hair? Why are ginger haired people.often discriminated? There are a lot of other characteristics than skin color we inherit from our parents, some are considered diseases, or syndromes, other not. The only difference with skin color is that we don't necessarily prejudice based on them, mostly because theses differences are less visible. Races is mostly a societal construct to discriminate people.
