Mulan,
This is a good question. I think the posts are in part reflecting the varied experiences of people here.
If you come cold to COC and have been someone who truly believed the GB were who they said they were, raised your kids believing that and on top of it know that really for you every other religion will not work, then yes, I would have to say that damage occurs, hopefully temporary damage.
I have known some that for them is was like having their legs cut off.
Now, I am not saying that reading the book is a bad idea, I'm just saying that we are all so different.
There are some good things about the Tower, association for one.
As has been mentioned, Ray Franz himself stayed until he was put out, and this even with his own expelling from Brooklyn and knowledge of the inner workings of the GB! How much harder might it be for some who did not have this knowledge accumulated over some 9 years experience with the GB, but who get this all in one shot!
It is a shock, a loss, a death for some.
I am happy to see that on the Commemtary Press site there are now essays discussing various spiritual topics, this is so good! It gives some who are leaving or left, a place to go for spiritual nourishment and comfort.
