This is a tedious post that isn't worth dealing with in-depth because I am skeptical that you even fully understand the issues in question. I'll bullet a response to you so you have the potential to possibly open your thinking. 1. Just because blue and purple are proximal on the color wheel, does not mean that blue and purple do not exist. i.e. The notion that a gradient exists does not invalidate the difference between proximal colors. 2. Even granted, there is a large geographic component to genetic distance clustering determined via SNP variation. 3. There have been specific studies that assess the American definition of race as comporting to genetic admixture. Individuals identified as black or white had perfect correlation to European or African ancestry. 4. The motivation to deconstruct race clearly pollutes this discussion. Everything can be deconstructed similarly. In fact, there is no real reason to have a sense of self at all given that your notion of being a distinct entity is a social construct. 5. The idea that races would have obvious phenotypic differences and similarities but could not possibly have other cognitive differences is inconsistent with basic reason and very metaphysical in thinking. There is absolutely no reason to think that evolution has no effect on the brain.
