A BBC story from 2006? Stories from her friends? That's the best she's got? Would be nice to see a real article on this topic with actual analysis and data. Of course it's stupid to label all men as possible predators, but there's another side to it: when a single pedophile can damage literally hundreds of children, who wouldn't have cause for concern?

It's extremely stupid to label all men as possible pedophile, and it's even really stupid to ascribe - to each and every pedophile - the faculty (let alone willingness) to be a predator.
Most children who are abused are abused by close relatives, so (as unpopular as that is) keep a close eye on other family members and your kids' buddies' parents, with a reasonable amount of concern. Teaching your children to fear all and every stranger, or any male adult, will deal considerable psychological damage to them; when a single well-meaning caregiver can damage literally hundreds of children in that way, who wouldn't have cause for concern?
