But what is the reader supposed to DO about it? Just say "ah, gee, that's too bad"...? It seems a bit artificial as some kind of proud announcement of survival. Sure, surviving a rape and not subsequently losing control of one's whole life may be something that indicates a strength of character. But to then need to announce it to everyone you meet... well... it'll certainly be awkward.
Seems like it is merely a way to force other people you don't know to be uneasy in your presence. It sets the agenda for what you want them to think about. Forces it. It's an aggressive and pushy, almost arrogant attitude.
If something like that ever happened to me, whether or not I ever become at ease enough to discuss it with people, I'm pretty sure it's not the first thing I would want people to know about me.
