In [Snatch], stereotypes reduced Irish Travelers to dirty caravan dwelling, thick accented, dim, brutal bare-knuckle boxers. Despite this, many Irish Travelers celebrated the Mickey O’Neil character (played by Brad Pitt) as a hero, as he was strong, attractive, an excellent fighter, possessed a strong concern for the welfare of his family, and, perhaps most importantly, he is victorious in the end, defeating the English, avenging his mother’s death, and making off with a lot of money.
As for how Irish Travelers contend with the virulent stereotypes, geographer David Nemeth relates a relevant point regarding another nomadic minority group, the Roma/Gypsies:
More traditional Gypsy power-brokers . . . may prefer being portrayed by the media as hustlers, even predators, than as the pathetic prey of Nazis and other racists. (cited in Hancock 1999a)
As the quote reveals, many will prefer the criminal stereotype over the romantic or victimized image as they would rather be associated with some sort of power, albeit stigmatized and illegal, which commands respect and/or allows one to be left alone due to the fear such stereotypes elicit. This also allows Irish Travelers to avoid, what Fanon describes in the postcolonial context, the psychological internalization of inferiority.
