My answer to all your questions is no. With a few exceptions, all the people in my life have never been JWs. And I love them all dearly. That having been said, sometimes I do feel that only another ex-JW will understand what that experience is really like. Which is probably a lot of the reason we are all here.
I welcome those who are here but have never been in themselves. People who come to this board have been affected by the WT one way or another. If not directly, then indirectly through people they love.
