We learned in sexual history class that in ancient Greek culture pedophilia was a very common practice and all that changed with the coming of Christianity and monotheism.
I still of course think it is wrong though, it's like those who are being judged because they are homosexual, you can keep telling yourself you are not gay and be with the opposite sex but how long can you keep it up? A lot of men have had affairs with other men and a stories of pastors who condemn homosexuality but have gay partners come out all the time . Not saying homosexuality is like pedophilia, just saying it is hard to stop sexual urges completely.
Also a lot pedophiles are in prison and not because they act on these urges but because of child porn and because the market is so large a lot of children are being taken raped and abused and filmed for their pleasure. If pedophilia is ever accepted I think more children will be at risk and like homosexuality, I don't think therapy will stop the urges from coming. I think we should isolate these people from society. Maybe not in prison but definitely not leave them in the streets.
