The sixth and the fifth centuries BCE were a time of constant re-identifications within Judean communities, a time when the Babylonian Exilic Ideology had captured central position in the Judean (Jewish) history and literature at the expanse of silencing down the voices of any other Judean community. Using social psychology categories of ethnicity and group-identity, Exclusive Inclusivity explores these internal polemics through the phenomenon of exclusivity, its characteristics and traits. By reconstructing boundaries of otherness, exclusivity constructs polarized positions through designations and counter-designations, arguments and counter-arguments, as also strategies and counter-strategies that each of the opponent communities advances to re-identify its own status as the in-group, and disregard, even delegitimize, all those considered out-group.
