I'm not pro-pedo, I think pedophiles can't help being attracted to children, but those who do not act upon their urges have done nothing wrong and should not be looked down upon.
Imagine if you are attracted to women (which you most likely are), and you for some reason could not have sex with them ever. It could be because no one would ever want to have sex with you, and prostitution was illegal and you would be condemned to death if you were to have sex with a prostitute.
Would you go to the length of raping a woman to fill your urges? Or would you masturbate to porn for the rest of your life? In the case of pedophiles, that porn would be drawn porn, like loli hentai, not real child porn.
