Hi James and welcome to the site, or should I say 'community', because this is a exactly that.
Although there are a lot of active/fading/ex JWs, there are also atheists, Christians, Jews and other non-christians. I think everyone here has a Watchtower branch of some kind, otherwise, why would they be here?
Myself, I have never been a JW, but I've spoke with plenty of them at my door, in my house and at the Kingdom hall.
My brother was left his faith over 20 years ago and his membership with the Watchtower has impacted our whole family [do I have to say in a negative way?].
I'm here to learn more about the JW mindset and to see how I could help him and his family leave 'The Truth' tm .
