Well, when you engage in fallacy by definition, who can argue with you? That's like arguing that no one recognizes that children exist as a concept when we define children as people who have not yet entered puberty and who are between the ages of 25 and 100. According to that crazy definition there are no such thing as children in the world.

Of these, only five individuals had DNA that matched an ethnic group different than the box they checked at the beginning of the study. That's an error rate of 0.14 percent. . . .
For each person in the study, the researchers examined 326 DNA regions that tend to vary between people. These regions are not necessarily within genes, but are simply genetic signposts on chromosomes that come in a variety of different forms at the same location.
Without knowing how the participants had identified themselves, Risch and his team ran the results through a computer program that grouped individuals according to patterns of the 326 signposts. This analysis could have resulted in any number of different clusters, but only four clear groups turned up. And in each case the individuals within those clusters all fell within the same self-identified racial group."
