Re-reconsidering Sleepovers

Recently, I had a friend post an article about reconsidering sleepovers. (The article can be found here)  I think the article makes some great suggestions about things to consider when having a sleepover, but something about the way the article is written rubs me a little wrong.  I grew up with a few kids that were not allowed to have or come to sleepovers but also went to more than a few myself.  I don't think one way or the other is "the right answer" for all people.  

My biggest concern with the article is that I get the feeling it is saying it's only safe to be at home--no one else is be trusted.  The article cites an article from the New York Times that reports only 8% of children are abused by strangers (and my understanding of this in the article is to not let your kids be alone with friends at their homes).  However, either article fails to acknowledge that most abuse happens within the child's own home. By family members. 

What are your thoughts?
