Just think about how silly that sounds. Imagine I said black is a lighter shade of color than white, it'd be ridiculous. Somehow such an outdated idea that human beings come from or can be separated into entirely different races, biologically different subsets of species, and that one is black and the other is white, remains in the American everyday semantics even though American academia has long moved past such a model.
Anyway, maybe this wasn't clear, when I say race isn't a thing I'm saying it's not a tenable scientific theory of human or biological taxonomy.
That doesn't mean that race as an erroneous social construct doesn't exist in the minds of people. In that way, race as a concept is still very much alive. But when someone says 'Asian is not a race', I think it's important to also note that black or hispanic or white, isn't, either, it's a social construct that is outdated, silly and that we should move past. Just like when people say 'homosexuality is a choice', when scientifically this is wrong, doesn't mean that this idea is not very much alive in the minds of some people. But when someone makes mention of it, it's important to note that it's a wrongful belief that homosexuality is a choice.
Some quick references for those who're unfamiliar with race as a social construct:
> As anthropologists and other evolutionary scientists have shifted away from the language of race to the term population to talk about genetic differences, historians, cultural anthropologists and other social scientists re-conceptualized the term "race" as a cultural category or social construct—a particular way that some people talk about themselves and others.
> Many social scientists have replaced the word race with the word "ethnicity" to refer to self-identifying groups based on beliefs concerning shared culture, ancestry and history. Alongside empirical and conceptual problems with "race", following the Second World War, evolutionary and social scientists were acutely aware of how beliefs about race had been used to justify discrimination, apartheid, slavery, and genocide. This questioning gained momentum in the 1960s during the U.S. civil rights movement and the emergence of numerous anti-colonial movements worldwide. They thus came to believe that race itself is a social construct, a concept that was believed to correspond to an objective reality but which was believed in because of its social functions.
> Craig Venter and Francis Collins of the National Institute of Health jointly made the announcement of the mapping of the human genome in 2000. Upon examining the data from the genome mapping, Venter realized that although the genetic variation within the human species is on the order of 1–3% (instead of the previously assumed 1%), the types of variations do not support notion of genetically defined races. Venter said, "Race is a social concept. It's not a scientific one. There are no bright lines (that would stand out), if we could compare all the sequenced genomes of everyone on the planet." "When we try to apply science to try to sort out these social differences, it all falls apart."
> Stephan Palmié asserted that race "is not a thing but a social relation"; or, in the words of Katya Gibel Mevorach, "a metonym", "a human invention whose criteria for differentiation are neither universal nor fixed but have always been used to manage difference." As such, the use of the term "race" itself must be analyzed. Moreover, they argue that biology will not explain why or how people use the idea of race: History and social relationships will.
