My cause is to personally recover and help my JW loved ones to think for themselves. It is not to bring down the Watchtower, even if I would love to see that happen.
My purpose at JWN is to share discussions with people that know where I am coming from and they know where I am coming from.
Many, but not all share my cause and purpose for their own lives. But really, we are a bunch of unherded cats.
I agree with OTWO. While I'd love to see the WTBTS crumble into dust, my main goal in participating in online forums and writing my blog is to support those who are "waking up" to TTATT.
