You're hilarious. First of all, nobody was disputing that the majority of the victims were male. But a 20%-female statistic is fairly significant.  

In addition, your age statistics are no different from the ones I presented, which show that the majority of victims were age > 7 to age 14. What percentage? 72%.  I somehow find it hard to believe that in any other situation these folks would be described as a blanket group of "teenage boys."
