Interesting post. I'm guilty of lumping them all together. I've had a LOT of experience with this kind of thing, although never being abused myself. Many of my friends have been. You make an interesting point about fathers who just reach for the nearest, most convenient outlet. My friends were all raped by their fathers/mothers/uncles. I always end up using the word predator when I discuss the subject with anyone. I suppose the urge is the same as rape...just being in control, the feeling of power. By your definition I would say definitely 4 of the 5 people I know in the WT religion were raped by Pedophiles, in that the offender either had access to sex within marriage but preferred a pre-teen, or the abuse was man-on-boy when the man was married, and the abuse lasted a while. At least one was attacked by a known person on the sex offenders' register. Interestingly, two of the offenders were JWs, one of whom is still a serving elder and has never been brought to book for his crime either by a judicial committee, or by prison sentence.
In some cases, where the children have been so-called 'jail-bait', maybe fully developed at the age of 14-16, it's definitely a grey area whether the offender is a pedophile. Anybody who touches a pree-teen needs their head examining. (by means of autopsy after they've been fried in the chair.)
