I'm probably digging myself into a hole here considering this forum, but it's a bit excusable for a 14 year old, especially one who was growing up in a household like this that doesn't know any better because of how closed off some topics must be. And honestly that goes for probably anyone of that age. Not denying the results can be horrific, but we're not talking about a 27 year old man doing this.
So it's excusable for a certain type of evangelical Christianity
to so fundamentally ill prepare a teenager as to make that teenager think it's okay to molest girls and for the family to think it's okay to deal with such matters 'internally'?
If that's the case, then their faith is worth f-ck all.
