Both William Shatener and Leonard Nimoy are, in fact, Jewish.  But the Trek culture that is closest to Judaism is the Vulcans.  The logical thought processes of Vulcans strongly resemble rabbinical (Orthodox) Judaism.  In fact, the Vulcan Salute is based on a Jewish blessing gesture.  If this really interests you, you can read my explanaton of it at <a href="http://www.pinenet.com/~rooster/v-salute.html"> The Jewish Origin of the Vulcan Salute.</a>

BTW, the Ferengi are NOT "Jews" - they are based on "Yankee Traders"  (episode TNG "The Last Outpost.")
