"she could get disfellowshipped for being here"
This is a red herring. You could get disfellowshipped for posting apostate posts, however, I have never ever seen anyone disfellowshipped for witnessing on the internet.
As an Elder, we had a person who posted at boards like this. He showed he was posting pro JW stuff. In the end, we could not stop him, however, he could not claim the time, according to the CO.
At any rate, we should want pro Jws to post here...so they can consider all viewpoints, IMHO
