Yes, I was amazed at the shunning, disconnecting, long periods of shaming and punishment before re-admitting, and disengagement from family members who leave or speak against the cult.
This corresponds with shunning, disfellowshipping and reinstatement, and cutting off ties with family or apostates. They use that word too. Both cults forbid talking to former members. Both spy on members they suspect of wrongdoing, and destroy families. Both have lavish headquarters and their own "language" which only members use. Both expect unquestioning obedience to the leaders as loyalty to God.
A woman formerly high up in SeaOrg was interviewed. She was sexually abused when underage. Her family was told not to go to the police, and that the elders would handle it internally. Sound familiar?
As I watched, I just kept saying, wow, that's just like the Witnesses- two cults which are so much alike.
