I bet she takes drugs and is always drunk too.
More than 35% of all sex crimes are child on child and more than 90% of offenders are boys.
The predominant age of the offenders is between 12 and 15. Most of their victims are under 10. Many are incestuous often stemming from naivete, curiosity and momentary indiscretion. Yet so many people believe that these children are monsters when as many as 95% are never accused of a sexual offense ever again. The recidivism rate is almost non existent, particularly when the parents get involved and get the kids mental health treatment. But hey their boys and have penises so they are by default abusers.
Welcome to the great new World in which women & girls are forgiven every transgression and shown infinite levels of sympathy but men and boys are deemed irretrievably disordered and evil.
What this entire episode shows is that any parent of boys who discovers this type of abuse, IE touching, even groping of a sibling, would have to be outright stupid to ever go to the authorities.
It is people like Katie the Arrogant that make the world a more dangerous place for all children.
