Good observation SC. I think it would be fair to say that more long standing JWs are MENTALLY LEAVING. They are there in body, but that's it. And frankly, they are not there in body as regularly as they used to be. HUGE problem with meeting attendance everywhere. Our circuit, meeting attendance 20-25% lower than publisher count.
So many have left mentally.
Regarding living a Lie and the blood issue, many will acdcept blood and say they are christian on their forms. The elders will never know.
I personally told someone that this many years ago, I said that this is what I would do. THEY eventually did it opon having a hip replacement surgery, a pioneer MS took blood. ....I found out years later that he did this when he thanked me for the advise.........
I think many in their 40s are aware of the flawed doctrines, but really, arn't all religions flawed?
