Oracle,
Your post describes pretty much how I feel about the whole thing except I have no family trapped in the religion. In my case though, when I found out the history and scandals in 2000 it just confirmed what I had already suspected. It still made me angry though. The waste of time is truly tragic! I do have to get rid of residual anger. In a way I feel if "I told off the right people" that I would feel purged. But, I realize that is not really possible because some of them are deceased and even if I told off certain ones that isn't going to change their feelings one iota. They have to come to the realization themselves.
I am working my way towards the 'happy and satisfied stage'. Like you, I will always be somewhat interested in the ex-JW subcultures to some degree - just not totally consumed.
