I would totally agree with this. Incrementalism. The way you really see this is by noting all the things that are asked of certain members in private. This is like Proverbs talks about in Proverbs 6 about the person who winks with their eyes, speaks with feet, teaches with their fingers - and how they sow discord.
Now in TWI, they teach that this verse is about the "seed of the serpent" men and women. How perfect. What a great disguise for nobody ever considering that is how they operate.
In the advanced circles, the elite of the elite, the pharisees of the pharisees, this is how it works. VPW, LCM, Rosalie whispers to a Cabinet member, a Region leader pre-prepares a Limb or Branch coordinator, then when in the presence of the person they have prepared in their hearts libel, slander, and false testimony against, a little wink is all it takes. A point of the finger, a pre-arranged signal, and people on queue attack with their libelous accusations. And people are demolished - sent away, kicked out, blackballed, labeled as 'possessed', shunned. I've seen this so many times.
Now in a normal Christian type of interaction and fellowship, you would never be able to convince someone to do this kind of thing. So how do they do it? Incrementalism. Teachings about commitment, step by step. The more committed you are, the more you want to be part of that 'inner circle'. The more you would justify to get there or stay there. It's a lust for power that drives it. Take PFAL, or the FNC, and you aren't even aware of this. However, as you advance, the programs stack up. Advanced class? Sell your house - get rid of your mortgage, become a nomad for the Way. Become trained. WOW / Way Disciple - now you're introduced to the more elite - you were willing to give up everything for a year and move wherever they told you. Corps? Same but even more - now you have people evaluate where you are every year and can tell you to leave or move. Clergy? You take a salt covenant with the leader to be bound to their will. Any misstep will have dire consequences.
I was discussing this with a psychologist over a meal once. He said that incrementalism presents choices in very small changes. Then you wonder how you got so far offline from normal. Every choice is not a choice between a scale of zero being the norm and minus 250 being your current choice. That would raise too many alarms. Its the choice between zero and minus 5. Then so on and so forth. And finally minus 245 to 250 is the choice faced. Not too different from where you are at. And spread out over time, the normal alarms in a person's conscience are bypassed.
Classic conditioning. Pavlov's dog. It's the tool of the cults. Behavior control. Control in general is the paramount thing. If you control the environment you control the person.
