The passage I quoted is one paragraph out of seven pages spent addressing the challenges in defining and analyzing ethnic groups and drawing conclusions from that data, not to mention numerous caveats and counter-examples provided throughout the text intermixed with his methodology and data analyses, or the extra text re-enforcing these problems in the conclusion -- not some brief cover-your-ass passage but rather one quote from a lengthy and detailed academic analysis of the problems inherent in this data. It would be obvious had you read the paper -- but you selectively pick and choose whatever information and "data" that supports your racist conclusions and don't examine it any further in case it would turn out not to, a trend seen in every source you have cited in this discussion.
