Confessing my geek heritage, I'd like to introduce Star Trek's Spock into the discussion--undoubtedly one of the most famous pop icons that immediately come to mind. The product of a human mother and Vulcan father has made him into one of the more interesting characters in Science Fiction and television--an individual of split cultural drives. Same with Star Trek--Voyager's Belanna Torres, human father and Klingon mother. The constant battle between her two competing sides directly influences her character and makes her fun to watch. By comparison, the other mono-heritaged members of the crews seem almost boring. This "mixed-blood" aspect adds spice to the show and inter-relations.
If PEACE PARTY's "racial identification" is anything like's Spock's racial identification, I'll take the results. Four TV shows, nine movies, and a billion-dollar licensing, er, enterprise. All are based on Spock's multicultural conflicts, without which ST wouldn't have achieved the iconic status it has.
