I am glad attitudes have changed, because instead of teaching a young girl a good lesson, you decided to perpetuate the wrong by ignoring it.
You could have told the 11 year old that she is growing up in a world where she can be subjected to violence because she is simply a girl, and that there are people out there that will try to blame her for it, and that its not her fault, and that these people are trying to make the world a fairer, safer and better place for HER.
But instead you decided to complain about OMG They used the word slut.
I am glad my parents were nothing like you. I knew about Tiananmen square when I was 7, my dad didn't worry about OMG some people are saying bad words, or showing bad pictures, and took me to the rallys anyway, and I learnt a lot, and what I learnt had nothing to do with bad words or people getting run over with tanks.
This sort of pretending to be proper as a proxy for real morality is disgusting and should be eradicated.
Anyone with a brain realizes that the use of the word slut was far less worthy of condemnation ( if any ), than the sentiment that the whole movement was against.

Just explain the word to them. When my kids starting taking the bus to school they heard all kinds of things from the older kids and they would ask me about it and we would just discuss it and it became a learning experience. My dad used to take us to Ottawa for protests all the time when we were little. Once he dressed all five of us in pro-choice t-shirts and we marched on parliament hill. I'm not scarred from learning what abortion was when I was 7 yrs old. Makes for smarter kids in my opinion.
