There is nothing I can add to this well-articulated, educated and accurate post. There are huge swaths of my past that I have no recollection of. An example of a shorter swath of memory loss for me: during a very traumatic event, I flew to another state when I was 13 years-old (with an adult and a sibling), was there for 2 full weeks, and flew back...but I have zero memories of any of those events. There are photos, but I do not remember any of it.
Regarding another post stating that those with trauma-related disorders never hurt others: one of my parents often blacked out during raging episodes (both parents grew up in abusive homes). I have siblings who grew up with me, in the same environment, that have lost custody of their children due to abuse/violence. One of those siblings also has blackout raging. The idea that no one who grew up in abusive/traumatic homes would ever hurt anyone else, especially a child, (in my experience) is inaccurate. We see it happen here almost daily. *I* never would, and never have, hurt a child...but I cannot apply how my brain formed (and what trauma response it resulted in) to every (or any) other person with a traumatic past. If those who grew up in abusive homes (or trauma, in general) never hurt anyone else, our crime rate would be significantly lower and Websleuths probably wouldn't need to exist.
