I think we could ask ourselves if sex dolls can currently
be used to "treat" those with the desire to sexually assault adult women (or men). I did a cursory look on google scholar and nothing really popped out
as obviously addressing this. I did see one long-winded social science science paper that beat around the bush
a lot, but it seemed to suggest that it can be useful for the disabled with few (if any) sexual options.
My completely-not-based-on-evidence-and-only-based-on-my-own-understanding-of-mental-health opinion is that I doubt sex dolls prevent
sexually deviant men from wanting sex with real women. I'd guess that even if you have sex bots programmed with a "personality" that people will still tend to view them as "not the same as a real woman." So I imagine that child sex dolls would be equally unsatisfying for a pedophile...in the long run, at least.
Despite all of that...the whole idea of censoring types of sexual aids, I'm not exactly comfortable with. If someone is bold enough to have possession of a child sex robot, then he or she should be able to...however, they are open to any criticism or social consequences that having such doll may entail. If a robot child, or robot sheep, or military assault rifle with a fleshlight attachment gets you off...go for it. But I reserve my right to get creeped the fuck out if I see it.
