"I think paedophilia has probably existed in every culture. Its something that exists in human make up. It's part of sexual diversity."

You are a thoughtful man, Al, but I think that this is beyond the pale. The exploitation of children for sexual gratification is extremely damaging to its victims. The (now middle-aged) victims of two of the men I referred to were damaged for life, some unable to form normal relationships. To dismiss that abuse as merely part of sexual diversity simply will not do. Unless I've misunderstood what you're saying, of course. Perhaps you'd care to rephrase.
