This point was raised in another thread vaguely, and wanted to try and expand on it.
The WT has said (and rightly so in my opinion) "that excessive use of drugs and alcohol can ruin your life"
In my eyes this is a fact.
This is where it starts to get a little suspicious, as they also say (or subtly hint at) "that if you leave the WT you will becoming addicted to Drugs and Alcohol and will ruin your life".
Its almost like a self fulfilling prophecy. As there are a LOT who leave the Borg and they do start drinking heavy or smoking, or taking drugs...or whatever.
The WT capitalizes on the fact that people want more freedom, and they subtly ingrain the thought that. drugs+alcohol=Freedom. But display it in a negative light. Albeit in the WT light.
Then these same people leave, they overindulge in these vices, and inevitably end up in a pretty crappy situation. I'm not talking homeless, but next to no disposable income, no career direction, and pretty bad health.
Then they remember. "The JWs were right all along, i am ruining my life..They warned me this would happen". They then return to the "Fold" and those aspects of their life get better. Better health as a result of taking better care of their bodies.
This process can sometimes take 20 years to complete. And then they say. "The JWS saved my life"
The result? These people, even though DFd, are still owned and controlled by the WTS, even though they do not associate with them.
It's pretty damn clever, and it's mind control on an Industrial level
There is a reason why the WT never highlights people who leave who start to eat healthier, exercise regularly, choose better life style choices, and get a good education. It's because these people would never return.
