I wonder what are the ethical implications of reading loli based mangas to ward of paedophilia tendencies though. :|
I really shouldnt be thinking too much about it, aren't I?
In terms of psychology, I am kind of interested in an exploration of this idea with actual science, but anecdotally I don't think it holds up. I've never heard of anyone seriously saying that they had trouble with violent tendencies that videogames or violent comics help satisfy. Never anyone saying that they felt they had rape tendencies towards real adult women curtailed by the existence of rape porn where people act out a rape fantasy.
It's only ever pedophiles who seem to assert that a fictional representation of their fetish is something that satisfies them and prevents them from taking the next step into true reprehensiveness.
