Not sure if the Jew and Virgo connection is that strong. I don't think Virgos smarts aren't the manipulative kind. Japanese and East Asian definitely, many Virgo guys marry Asian women (Gandolfini comes to mind) and the overall cultures seem very Virgoan.
Are you comparing race/culture to astrology? It's actually an interesting topic but I see a lot of abuse coming from this based on stereotypes. Unless you have the exact birth time of the races. The bible may help you out with this.
