I'd seen this video before, and it does a great job of explaining it. I know a fair bit about this because I used to work with kids who were reporting this kind of abuse. (I didn't directly interact with the kids, but I was sent the DVDs of the police interviews to type the transcriptions of them.) I'm by no means an expert, but between that, my own experience with some weirdness, and the fact that I know someone who sexually abused kids (she did go to jail, thankfully), I know stuff about the subject from a lot of different perspectives.
It's interesting to me how so many people out there claim to be so knowledgeable this and just ~*~know~*~ the accusations must be true when they don't really know much about this issue.
