I think that my discernment is, sadly, born out of experience. I think it is a skill picked up on the battle field.
I never claimed that all pedophiles were homosexual, far from it. The man who severely molested my mother was her father, and he was a literal member of the "sex before 8, or it's too late club" Yes, there is such a thing, and it's membership is not limited to heterosexual males.
I claim that any time a person bends the rules of sexuality put in place by their creator, and goes further and further down the path of a life of sexual deviance-that all bets are off. Just like the man that is at first content with a little soft porn, then needs more hardcore, then needs the real thing, then starts "flashing" people, then starts molesting his daughter, then goes for more and more and more... Ever seen the interview with Dobson and Ted Bundy? Once you tasted of perversion of purity of anykind, it typically doesn't stop right there. A little peek or touch isn't enough anymore. Same thing with my own father. And the same thing with my daughter, while in the care of her idiot dad, her gay uncle molested her. He wasn't the "flaming gay" we all know now back then, just a very confused boy.
We can't limit pedophilia to heterosexual men, or women for that matter. Of course it's not a given that a gay person is also a pedophile, and that wasn't my claim. Yes, pedophilia and homosexuality are different, so is pedophilia and beastiality- but sexual perversion blurs the lines of what is right and wrong and there is a lot of crossover. That is my experience anyway. That experience is based on women I have worked with ( I did not counsel their male partners since that wasn't the set up in place) and my own battered life as sexual prey, as well as my daughter's. It absolutely amazes me that sexuality is such a monstrously important issue in our society. it's just sex, whether you do it with men or women or both or animals or tables or whatever. Is there nothing more to the human existence than sex? There are those out there that would have us and our children believing that is the case.
Celibacy in our society, here in the US anyway, is looked upon as weak. In reality, it would take great care, determination, committment and a strong Faith to make it happen. It's a lot easier to go with one's urges, I should think.
I do not mean to offend, or to suggest that all gays/lesbians are also pedophiles. Nothing could be further from the truth. I do contend that when you step into the cesspool of sexual perversion, you are going to be covered with what's in the pit and it will affect everything you see and touch. One has to get out of the cesspool, cease going back to it like a dog to vomit, and focus on their eternity. That's hardly limited to homosexuality.
