Just about all the points have been covered, but just to add my 2c...ISOCF in my opinion is a must read for any xjw who ever considered themselves an 'all the way in, fully indoctrinated jw.' COC helped greatly in addressing the gnawing doubts I had, but could never be crystalized because I never had the info. Also helped me confirm that the org was far less than claimed.
But ISOCF was a piece by piece dismantling, that helped to address the question and doubt that lurked in the back of my mind still..."With all the mistakes/mishaps/misguided efforts, what if they still are right?" The chapter on argumentation and manipulation is a must imo for any former died in the wool exjw, regardless of what belief system a person now holds. In order to move on, it was what was needed for me as a raised in jw.
For those who choose to still follow Christianity, I believe that the view presented in ISO is a comforting one and one more in line with the spirit of Christianity.
Doctrinally, I am at peace with my current position. The only ties I have that concern me are the emotional/family that are still in.
