Yes,,probably it would only be one person, probably the PO or CO or an elder. I don't expect it would get beyond that. However, there are individual elders re-evaluating,,it does happen, I know several in the past that used to be elders.
I know some hope for a 'mass exodus' some day. However, in the mid-80s many of us hoped that too. Many wrote some government officials, and my brother did get a letter responding from Jon Kyl, Arizona Member of Congress, no opinion but a thank you. We (anonymously) even sent all the elders in the congregation (to their own home) a "Crises of Conscience" book each. We also sent one to Michael Jackson. We got no response but it wasn't returned either. Also, in '87 we had a huge gathering at a convention room at a hotel in Metrocenter, Phoenix. of ex-JWs, including Ray Franz, James Penton, Ed Dunlap, Ron Frye and several others. The television came out to film the group and did a news on that. A talkradio show was done that same weekend. My dad and brother had a huge full page article in the Phoenix Gazette then. Also, a couple of other ex-JWs, one who comes on this site here a lot had a huge article on him as an ex-JW. (I will scan some of these articles to send if you wish.)
I had hoped for a huge impact with all leaving then, with Ray's book and other books that the organization would be effected. But it didn't seem to. The organization grew ('75 a little over 2 million, now over 7 million) and was buying dozens of high end Brooklyn property). Was discouraging. It would have been so great to have the Internet then and YouTube. I, my siblings and our dad moved on with our lives, but not truly forgetting our past JW lives.
Of course, things seem to be different for the Watchtower now. Seems to be many factors/circumstances. Internet and YouTube are great. I am hopeful again. I cannot dare hope for a 'mass exodus' yet but I am 'watching' and willing to send letters again and emails. (Any who have addresses or emails for me, please PM me.)
