"This book departs from several assumptions with the explicit intent of changing them. That all Jews came from Eastern Europe and spoke Yiddish. That Jewishness is only religion; that secular Judaism is a contradiction in terms; that real Jews are born Jewish. That calling (all) Jews "white" explains anything. That calling (all) Jews people of color explains anything. That American Jews and African Americans used to be best friends and are now enemies. That Jews and Arabs were always enemies and could never be friends. That life in the diaspora has always been a vale of tears that all Jews aspire to escape. I write this book to overturn these assumptions, but also to strengthen the identity and practice of Jewish antiracism, including the often buried strand of economic justice. To heighten understanding among Jews of diverse backgrounds/cultures/ethnicities that we need each other in part because of our differences. To help Jews grasp that those Jews who are cultural minorities within a hegemonic Ashkenazi community are often best equipped to help the Jewish world reckon with our multiculturality, and to know that this multiculturality is an enormous asset when it comes to combating racism and anti-semitism and to building social justice coalitions. I name this identity and practice of Jewish anti-racism Diasporism."
