The Wikipedia article basically says that the definition of a pure race and pure individuals was a strawman - there never was such a scientific definition. Thus the Wikipedia article merely points out the strawman definition, but says that "such groupings lack a firm basis in modern biology" - which is exactly what I was trying to convey to you. Lack of firm basis does not mean lack of a plausible definition of race.
Race is a fuzzy concept and the races of individuals are fuzzy as well. But fuzzy logic would be an extra leap in understanding, at first you need to understand the basics of PCA (Principal Compoent Analysis).
