I don't see the problem.
It's not just that JWs follow the Bible, it's the pattern of how they interpret and apply it that gets to the heart of what the organization is really about. As much as I have a distaste for other churches, you can at least go into many of them as a non believer and not be hammered over the head about how disgusting and broken you are. If curious JWs can start to see the other side of things, their empathy can lead them in the right direction.
