It's a different kind of trauma when you cannot remember or even recall what actually happened - you're bothered by the fact that you can't remember rather than by the negative experience itself. There's quite a difference in the degree of unpleasantness between "being raped and reliving the experience in nightmares" and "finding out that you were raped at some point in your life and have no recollection of it whatsoever". I see your point though.so are they also going to erase the memories of everyone that knows about it to? because it would really bother me if i had the feeling that everyone was hiding something from me like the fact that i got raped. not that i did, but you get my point. eventually you would find out again.
