Not every pedophile is a rapist.

[Napoléon]

These weird scenarios are so hard to answer. I would argue that a 14 year old couldn't consent to donating their body to the 30 year old in the first place but without considering any outside factors I don't see why a 30 year old in the body of a 14 year old couldn't consent.

For arguments sake ignore the actual logistic and medical issues with putting a 30 year old brain into a 14 year olds body, that's not really the point. My point is, if we had a 14 year old, or 12 year old, or hey, fuck it, a 7 year old, with the intellectual capacity and ability to give consent of a 30 year old, would we still look upon having sex with said person as morally wrong?

Well, if yes, why? That would indicate to me there's more to this whole issue than just ability to give consent, which I find curious. I'd like someone to elaborate on that if they think it's the case.

Alternatively, if no, then it indicates the only factor in this is the ability to give consent.

I guess what I'm getting at by asking the question, is are there more factors than just consent? Are there strictly biological ones, are there some other ambiguous moral factors?

I find this thread topic quite interesting, I think the reason is because it's an incredibly grey area and it's difficult to draw lines that aren't arbitrary.
