1. Fear (of God, biblical doctrines,elders, slander, where to go from here, etc...)
2. Family and Friends (shunning and cutting them off)
3. Financial (binds and obligations)
In my own personal situation some of the above has kept me captive in this high control group for many years.
For me... the slander and where do I go from here are factors. But the shunning policy is by far the biggest fear I have. The thought of all my relatives shunning me is beyond the pale. That's why I consider the watchtower organisation as a bat shit crazy cult/printing corporation .
