If you can fill out a confidential document and not break into a sweat when answering the question "What religion are you?" and NOT say JW then you are an exJW
I was DFed when I left. But the WT mindset was still in me. To the point where I actually wrote a university paper defending them and their policy on blood.
It took 10 years to finally get the WTS out of me. Although I was DFed and had no intention of going back I would have squirmed when answering that question. I would not have said "JW" but I would have been pretty uncomfortable about it
