True, in plain numbers. But It's the percentage of offenders in each group that's most telling. It's much high in the gay community. In fact, I'm not at all certain it's even considered abuse unless it's blatant rape.
True, its why percentages are more important. Unfortunately for political reasons, the data is very mukry, and not just due to the pro-gay crowd.
Underage girls who get pregnant often go for abortions, and orgs like planned parenthood will often obscure the relevant info (hiding or blurring many cases, destroying evidence, protecting rapists and those who commit incest, etc.).
I have no doubt that the percentage of molesters is higher on the other side of the line, there is a reason gay rights groups consider lowing the age of consent to be a part of their agenda. That said, the true numbers and percentages will always be a mystery, but heterosexual molestation is not that rare unfortunately, its just very hidden, by the various special left wing orgs to protect an industry that profits from it.
