I`m looking for more examples of this phenomenon of feeling the need, due to your unusual background, to prove you are X enough. Perhaps actress Halle Berry? Maybe Zach de la Roccha of Rage Against the Machine is an example. (Daniel Day-Lewis is an amusing example of something slightly different: a complete insider — his father was Poet Laureate of England and his maternal grandfather ran England`s top movie studio — who has used all his Method acting skills to convince himself that he is a much-discriminated against Irishman). Or Eamon de Valera of Ireland, although I`m not really familiar with his personality. In a different way, Hitler, Napoleon, and Stalin were all from the peripheries of empire.
I think there must be more. Do you know of any?
Can you think of any examples in movies or novels? I heard today about a 1993 movie called either "Bound by Honor" or "Blood In, Blood Out" that is a huge favorite among East LA chicanos. The main character is a completely European looking Mexican-American who must constantly act like a total cholo to prove he`s Mexican enough.
