I missed the original response, which has since disappeared. However, I'm still pretty appalled by this response.
You can dress it up however you want, but it is still victim blaming/shaming, and that is not OK. The Dame's argument seems to be that OP shouldn't have done something that COULD have led to something bad. By that logic, I shouldn't leave my house because I could be hit by a car/raped/abducted by aliens. It veers dangerously close to the "she was asking for it" argument.
I have played that game many times. Sometimes, with close friends, it got racy; other times, it was a getting-to-know-you game with the "raciest" statement being something akin to "never have I ever eaten something from the garbage." Just because the Dame and her children have always experienced the game with a sexual component does not mean that the same is true for all of us. Given that we don't know what the OP's experience is, it is foolish to assume that she knew it "had" to get sexual, especially because apparently many people told the Dame that they did not have the same experience. (Of course, I can't check because the originals are gone.)
The Dame's whole argument is based on the idea that the poster was doing something inappropriate: playing a game in a bar meant to reveal details of one's sexual past. We have absolutely no way of knowing whether that was true or not. It could have started off innocently enough (she did say that they were a group of friends just trying to catch up with each other) and that could have been the first sexual question. At that point, nothing she could have done could have preserved her secret because her friend likely would have said something even if she stopped playing.
Again, and I can't state this enough, victim blaming is NOT OK. She was not engaging in any risky behavior. Just because you and yours are constantly surrounded by vulgarity does not mean everyone else is.
"This site raison d’etre for years has been the focus on one’s own personal responsibility for behavior." Perhaps the Dame could take her own words to heart and simply apologize rather than trying to backpedal and justify.
