tyrone, nobody wants to accept that they are in a cult, at least until they begin to wonder if they are. It's an emotionally charged word, along with brainwashing, that brings up images of Jonestown and other atrocities. Maybe you would prefer the terms "high control group" and "thought reform"? There is a checklist, provided by Dr. Michael Langone, for such things. While not evidence, it is thought provoking.
The group is focused on a leader to whom members seem to display excessively zealous, unquestioning commitment. Typically, the leader is alive, but in some cases may be deceased, but his or her “message” (belief system, ideology, touted practices) is still upheld as the Truth, as law.
Questioning, doubt, and dissent are discouraged or even punished.
Mind-altering practices (such as meditation, chanting, speaking in tongues, denunciation sessions, and debilitating work routines) are used in excess and serve to suppress doubts about the group and its leader(s).
The leadership dictates, sometimes in great detail, how members should think, act, and feel (for example, members must get permission to date, change jobs, marry; leaders prescribe what types of clothes to wear, where to live, whether or not to have children, how to discipline children, and so forth).
The group is elitist, claiming a special, exalted status for itself, its leader(s) and members (for example, the leader is considered the Messiah, a special being, an avatar; the group and/or the leader is on a special mission to save humanity).
The group has a polarized us-versus-them mentality, which causes conflict with the wider society.
The leader is not accountable to any authorities (as are, for example, military commanders, and ministers, priests, monks, and rabbis of mainstream religious denominations).
The group teaches or implies that its supposedly exalted ends justify the means (what members are expected to do). This may result in members participating in behaviors or activities they would have considered reprehensible or unethical before joining the group (for example, lying to family or friends, collecting money for bogus charities).
The leadership induces feelings of shame and/or guilt in members in order to influence and control them. Often, this is done through peer pressure and subtle forms of persuasion.
Subservience to the leader/group results in members cutting ties with family, friends, and radically altering personal goals and activities that were of interest before joining the group.
The group is preoccupied with bringing in new members.
The group is preoccupied with making money.
Members are expected to devote inordinate amounts of time to the group and group-related activities.
Members are encouraged or required to live and/or socialize only with other group members.
The most loyal members (the “true believers”) feel there can be no life outside the context of the group, believing there is no other way to be, and often fearing reprisals to self or others if they leave or even consider leaving the group.
I could go through the list and demonstrate how the WTS fits every single one of these, but that defeats the purpose. These are things that you should investigate yourself, not blindly accept the answers.
