It is pedophillia when it is pre-pubescent children. Once you get to the 12-16 year range it is technically pederasty. From what I have seen most of the Church cases involved pederasty and not true pedophillia.
The "latent sexuality" cause as the reasoning for the molestation in the church gets more support if most of the cases are pederasty and not clinical pedophilla. The reason the pedo term is used is because the media is quite frankly, lazy,
You make a good point.
According to what I recently read,the majority of abuse is on post-pubertal children around 16 or 17 and they term it "hebephilia". When it's children of that age than it would be homosexuality. One estimate seems to be around 3% of priests are involved - a smaller number then the general population.
You are right though, it's a lazy media - pedophile is much more attention getting as well.
Either way though, the priests are abusing a trust.
