I don't believe they think there's nothing wrong in it ... society has shown repeatedly that most people disapprove and they must be aware that it is a punishable offence. But clearly some find it difficult to suppress, since it is a 'natural' urge in them.
This is indeed quite a problem, Len. Since I believe that our sexual natures are largely 'fixed' by our mid-teens, and no amount of therapy is going to turn homosexuals into heterosexuals, by the same token, those who are attracted to juveniles are likely to continue to be sexually aroused by them, no matter what. I suppose with most of us, we are likely to find the most desirable partner to be someone who not only turns us on sexually, but shares common interests with us on a wide variety of matters, and that 'maturity' of sexual taste lies in moving towards that. But the instantaneous 'turn-on' is likely to remain the same throughout life. Certainly the case with me.
Some people argue that the pederast gains sexual stimulation from a power relationship, and it is certainly easy to dominate a child or youth. Maybe some education towards 'normality' might occur there. But I'm not so sure - I think, like you, that the pederasts' sexual feelings are entirely natural to them.
However, since we recognise that such relationships are almost universally harmful to children, probably for the rest of their lives, the only socially acceptable behaviour for pederasts is celibacy.
The composer Benjamin Britten was unquestionably a natural pederast. Even though he had a life-long relationship with the tenor Peter Pears, there is every indication that he harboured deep-rooted sexual longings for young boys. He managed to sublimate his desires, and though no doubt he sought out the company of young boys somewhat obsessively, he never interfered with them sexually, and it is quite likely that many of these young boys benefited greatly from being in the company of a genius.
