Sectarian Discrimination is bigotry, discrimination or hatred arising from attaching importance to perceived differences between subdivisions within a group, such as between different denominations of a religion or the factions of a political movement. The ideological underpinnings of attitudes and behaviors labeled as sectarian are extraordinarily varied. Members of a religious or political group may feel that their own salvation, or success of their particular objectives, requires aggressively seeking converts from other groups; adherents of a given faction may believe that for the achievement of their own political or religious project their internal opponents must be purged.
