Umm. I reject the JW's, and I know longer believe in anything spernatural. Having said that, and in the interest of keeping things real: As a JW for decades, with plenty of pioneering time, I very seldom met any person who had read the Bible as much as i did, or as much as my friends had. When this rare event did happen, it usually involved a spirited but futile argument on the trinity or other such abstractions. It's misleading to suggest that JW's are less well-read than average members of other religions. Large numbers of people don't know a damn thing about their religion. It's also pointless to suggest that JW beliefs, which are quite silly, are somehow more silly than anyone else's. Really? Wine turns into Jesus' blood? The Rapture? The JW's reject certain silliness, while embracing others.
I do feel for that woman. Doubting can be a terrible feeling. But it can lead to something good. I hope that she's able, finally, to escape from the whole business, from god, demons, everything. That's true freedom.
