The Ancestry DNA results show that there is a sub-population of Jews (Ashkenazim) who share certain identifiable genotypical patterns. I would go one step further to say that these genotypical patterns include a commonly shared Near Eastern ancestry (however, it is important to note that this Near Eastern ancestry is not the only phylogeographic ancestry shared by Ashkenazim). Since no population is 100% homogeneous genetically, the facts presented by DNA evidence don't mesh well with socio-political concepts such as race, nationality, and minority status-- when speaking about genetic genealogy I avoid any of these terms.
