1. Race as a social construct. It does exist in that capacity - as an extreme example Irish were not considered "white" in America (google for some "hilarious" images from "back in the day").
2. Race as a biological reality. This is a touchy subject for a variety of reasons. But that doesn't mean that well documented taxonomic differences between human races are "fake". They do exist and are more than "skin deep" - things like bone density, cranial capacity, maturation etc etc. Ask your dentist if he can tell by looking at someone's jaw x-ray whether it belongs to an east asian or sub-saharan african.
