I disagree for this reason: Society would have to be more understanding of their desires, for that to actually be possible. They would have to feel comfortable enough not to be shamed and hated. If we get to a point where we are accepting of admitted pedophile...err, "desirists", we're moving in the wrong direction, and that starts the chain moving towards acceptance.
It's all well and good to think about it from a more intellectual standpoint, of research and whatnot, and trying to crack their code, but you have to be realistic as well. You want to live next to non-offending, self admitted pedophile? You want anything to do with them at all? I would wager that's a solid "no", which is why what you're proposing will never ever happen. That's a stigma you can't erase, nor should we be trying to.
Like I said earlier, you want to research them? Plenty of them in prison who can tell some therapist all about it. I'm also sure there are plenty on the outside who have divulged some of these desires to their therapists as well, and that's all fine and dandy for them, if they can keep it under wraps. However, if I hear anybody near me is expressing their desires to fuck kids to anybody, including their therapist, they're not getting any "understanding" from me, and I'm damn sure most of society feels the same way too.
