Two points:
1) As best I can tell, She wasn't trying to "show her". She has moved on from the "prove you wrong" stage of leaving the Watchtower to the "oh, you poor wasted life" stage. It's progress.2) You'd be surprised what wakes a person up. One user on JWD was brought out by a billboard that simply said, "607 BCE?!?" For me, that wouldn't have meant a thing. But it caught his eye, he did some research, and realized the 607 date was baloney. He got out. Different points appeal to different people. Here's a woman that says she understands the Bible perfectly well with the help of prayer. That stands in contrast to the normal JW view of people that they read the Bible but don't understand it. It may put her on the path to questioning other things, and lead her on out.
i felt the exact same way when i read defd's post.
defd: i'd say most of us are not the typical apostates we were warned about as jw's. we were taught to HATE people who don't even almost hate us. just because they disagree with what they were taught as jw's...
