Stephen Bloom is a Jew from California, now living in Iowa City, and the author of “Postville: A Clash of Cultures in Heartland America.” Bloom tells Jim Fleming that the Orthodox Jews who moved from Brooklyn to Postville to run a kosher slaughterhouse have no interest in assimilating and becoming Iowans. They are aloof to the locals to the point of rudeness, and not the kind of Jew Bloom is or has any interest in being.
