If they achieved it, I would not give a shit anymore. In the first place I worked hard for it not to happen, on two occasions they thought they had me and could prove I was an Apostate. I wriggled out of it both times.
Now, it would be a pain in the arse, because my JW family and other Jw's would shun me, so I do not seek it.
They would find it an incredibly wearing and long drawn out process if they went down the road of trying to DF me.There is so much excellent advice on this Site and others, I would use every trick in the book.
Finally when they had given up, I may well request a meeting with several Elders, and when there, light up a HUGE CIGAR ! and tell them to DF me for that !
