I don't think it's accurate to say that most male pedophiles are homosexual pedophiles. The only reliable observation according to USA Today is that most pedophiles are male.
When you factor in the statistic that one out of four women are molested before the age of 18, whereas one out of ten men are molested before the age of 18, obviously more girls are being molested than boys. That would seem to negate the idea that most pedophiles are homosexual, since more pedophiles seem to be targeting girls than boys.
Change the age of the victims to "younger than 10 yrs old" and see what you get.
Majority of abuse victims IN QUESTION are males or not?
