Whether you are df'd or not most JW will have nothing to do with you if you leave the organization. It's the price you pay for freedom of thought and being true to yourself.
The Watchtower says that they have no membership so I've always felt how can they kick you out of an organization that you never really joined. If they say but you were baptized I would reply that the baptism was obtained under false pretences. They misrepesented themselves as a truthful organization that God select. They aren't truthful and it is easy to prove that God never selected them. They lied on the contract so I don't see why anyone would consider it valid.
Just how I feel I'm sure not everyone would agree.
One more thing as far as dfing goes I df'd the Watchtower. Not the other way around. And I highly recommend it.
