It's only fair. The US rates violence in movies actually very low compared to europe. In the US sexuality is a bad thing, but violence isn't apparently.
People like to bring this up as if Americans have it backwards. But does anyone ponder whether it's actually the sophisticated Europeans that have it backwards?
When I look at the things that can derail a young life the various pitfalls of sex (including violence and harassment) are much more likely to directly impact a teenager than guns and 'splosions.
And remember, these are all real little girls. It's not wrong to say that the real life people that did this to real life little girls exploited them.
