I can see where this sentiment is coming from, in that there's very few objective markers (genetics, location) that can fully describe race. Further, I agree that studies should avoid generalizing and assuming that those markers are always there.<p>However I firmly disagree with the combative headline -- race is a very much a _real_ social construct. Just because it's a social construct doesn't make it any less real, identities and personas do have pretty strong experience's in one's social life which can impact their health, well-being, etc. I don't see why this opinion piece has to describe it this way, it minimizes the real impact these social experiences have.
