"In any crime - follow the money"

[Darkstar]

What kind of club have you been a member of then that collected dues? Yeah. Voluntary if you want to remain an active member of the club. If you don't want to pay, then you get kicked out.

The point he's trying to make is that normal clubs don't tell you that you are going to face eternal damnation if you don't remain an active member, and remain totally obedient to their figurehead. That is called a cult. I think the word 'cult' has come to be associated with the suicidal ones, but it doesn't have to be suicidal to be a cult.
