the sex cult pattern isn't just a rare occurance unfortunately. it's practically inevitable in any organization which 1) asks that its members become deeply emotionally invested, 2) places emphasis on stability, unity, and not rocking the boat, and 3) concentrates real power in the hands of those few with the most time, energy, and charisma. Mainstream political parties notably give salaries to the people who keep the party actually running. This allows individual members to subsist on more than the good feelings they get from seeing their friends at meetings, as well staves off the fear that the entire organization might collapse if an abuser is challenged.
