I think it depends on the person. My Dad says the same thing. But, it is honestly the real deal and not dub talk. I mean think about it, this religion has been a giant part in people's lives. Some people would be scared not having the witnesses telling them what to do. I love the part in Shawshank redemption when RED is talking about being institutionalized.
Even if a person is not the greatest witness, that can almost be worse. The don't have a great deal of knowledge, but have always been told you need to be a witness to be "saved". A person will do tons of "sinning", but still have that hope of becoming a good witness so they wont be killed on D-day.
I remember when I first started having doubts. I would always read on here that it was a cult. I would laugh and say these people are just crazy and dont know what they are talking about. The more I look with a clearer mind, the more I see a cult. It may not be the Jim Jones group, but it is definatly has cult tactics. Just as you were trying to talk to her about the blood issue, she literally covered her hears. Thats the ORG comming out.
Just as when you were a DUB and prayed that people would come to their senses and do better in the ORG, you have to just hope she will come to her senses and realize the TRUTH.
My dads big hold up is that there is no other religion to go to. I have yet figured out a way to get him to realize, he doesn't need another place to go to.
You should probly take your own suggestion and go easy with her. Just make comments here and there that are not nessicarly targeting the witnesses. You never know when something might get passed the organization wall.
