It's emotional and spiritual blackmail. Holding a gun to your head and stating that "You have free will to leave any time you want, but you loose your family if you don't decide the way we tell you," is NOT free will at all! It's forced compliance thru threats which they WILL follow thru with. Hence, human rights violations.
After watching Leah Remini's doc, I was telling my mom (VERY devout JW) that some see DFing as emotional blackmail. She argued it was not, you are making the choice. So I gave her a real life example. I said you know mom, let's say you want to leave the town we live in. You are done here. It's fine you can leave anytime you want. But if you leave you will never be able to see me or talk to me again. Or your grandkids. Or your great grandkids. Because we are staying here. We like it here. We like the lake and the weather. We like the museums and entertainment. We like the school systems. So we are going to stay. But you can go, here are your tickets. And I placed imaginary tickets on her leg.
The look on her face was priceless. She swallowed a lump. I then said, to ease her mind, cuz I'm PIMO, I'm not saying that *I* think it's emotional blackmail, but this is why some say that it is.
