Spot on. It's all about not entering into their world. There's so many language traps, so many buzz words and phrases that one can easily find oneself saying such stupid things as "I'm leaving the Truth!"
You have to move away psychologically and verbally. If you are determined to get into dialogue, and this includes dialogue with yourself as well as JW's, Jehovah must become your Creator, disfellowshipping must become excommunication, the ministry work simply door-knocking or canvassing. There's many more that can be added, I'm sure.
