Certainly it is responsible. What I have been struck by as I have come to know more about and understand people who choose paedophilia is that they let themselves be too much defined by other people. That is usually an essentially negative definition. Paedophiles spend a lot of time and energy defending their choice. I don't think that a paedophile needs to do that.
Paedophiles can boldly and courageously affirm what they choose.
They can say that what they want is to find the best way to love. I am also a theologian and as a theologian, I believe it is God's will that there be closeness and intimacy, unity of the flesh, between people. Paedophiles are too defensive. You're putting me in prison, you're doing all these terrible things to me. I have to define my love as being in some way or other illicit.
