As a kid that grew up during the beginning of this whole ordeal (as we're trying to label it), I have this to offer:
I'm not saying that this kind of thing is ok for a 10 year old, but I was ten or so, and I lived.
I'm going to say the same thing I say every time someone brings up some sort of discussion about "kids these days" or anything relating to the topic - they are your children. This means it is your responsibility to ensure that they are capable of dealing with the way the world is - not anyone else's. Hiding the world from them won't make it go away.
