@joefromchicago,
That's not how I remember it. I remember him arguing that being a pedophile is not a choice and that merely consuming CP was not unethical as long as the viewer harmed no children. He extended this ethical position to mean not paying for it and thereby not funding it but merely consuming it.
I managed to convince him to reconsider the bulk of that position when I argued:
1) That just knowing that there are people out there that may be viewing the abuse could be deeply harmful to the victim.
2) That allowing such consumption would make it more difficult to combat the victimizations in the first place.
3) That a pedophile should not seek to satiate this particular urge through pornography. That it could lead to an escalation of the paraphilia if it is not enough, through desensitization etc. On this point we had some disagreement, as he asked for science to substantiate this claim and I was unable to provide anything convincing (by its nature it's not an easy thing to study and I know of no such study that is conclusive).
4) That he may not have had much of a significant chronophilia in the first place (he was very young himself, and after someone "outed" his Facebook page it became clear that he looked even younger) and that when a teen who looks 12 says he's attracted to girls that age it's not necessarily pedophilia, at the very most he may have had hebephilia but his explanation that he was occasionally attracted to girls that weren't chronologically discordant may indicate that this was just a phase of his where he, due to his awkwardness, was going through a phase. He didn't really respond to this suggestion but it's still one I find probable. That he was as much a socially awkward teenager that was developing slowly as he was a person afflicted with a chronophilia.
