Believe, you're not hijacking. I think it's an important point and I thank you for clarifying. The author has a valid stance. Like you (and without reading the book), I don't agree.
I think that what NMKs and I are saying is related, though. If we, as survivors and their loved ones, give an inch, we think we'll lose a mile. We can't concede that some people possibly hyper-focus on their abuse and get stuck. There is certainly truth to the pitfall of defining your life by the most traumatic event you've experienced. I would assume that the concentration camp survivors, POWs, war zone survivors, and others who have experienced the greatest trauma imaginable who have done the best, have addressed their trauma and moved on. They have sought help and relied on support systems but also filled their lives with vibrant actions. They've embraced life rather than staying stuck in the mire of agony. I do agree that trauma does not equal a lifetime of misery. It does call for a lifetime of fighting back the demons, though.
I get all that but I do think that childhood sexual abuse is a Pandora's Box. Once the sexual feelings and physical and emotional responses are let out of the box, there's no stuffing them back inside and locking the box. A piece of the victim has been stolen, cut off, changed. They will continue to grow and to live but will take another form than they would have had they not been abused. Therein lies the crime and the need for societal response and sanctioning.
We got started on this discussion by the misuse of a single word; "masochism". Even though survivors can move on and achieve peace and happiness, they still have to be hyper-vigilant. We are the gatekeepers. We are the canaries. We are the sentries who are entrusted with alerting the public to any seepage in the dam against evil.
