Title:
Jehovah%27s_Witnesses

Context:
Sociologist Rodney Stark states that Jehovah's Witness leaders are "not always very democratic" and that members "are expected to conform to rather strict standards," but adds that "enforcement tends to be very informal, sustained by the close bonds of friendship within the group", and that Jehovah's Witnesses see themselves as "part of the power structure rather than subject to it." Sociologist Andrew Holden states that most members who join millenarian movements such as Jehovah's Witnesses have made an informed choice. However, he also states that defectors "are seldom allowed a dignified exit", and describes the administration as autocratic.
