I'm not sure. 'Child fucker' feels like it slips past more emotional and political defenses than 'child rapist'.

Rape is largely considered okay in this culture, and there's a lot of stigma against not ruining a promising young man's life (like that rapist Alan turner guy who did that rape) over a little rape. Rape is a mistake a young man makes and its all fine as long as we don't think about it too much. All the emphasis is on victim and perpetrator and victims are losers, disposable, while perpetrators are winners and deserve our sympathy.

Fucked highlights that somebody came, somebody had a nice time on purpose-and that's a sin, even if they hurt someone else to do it.

Highlighting that the person hurt was a child and creating uncomfortable images in those with heightened disgust reactions is just a bonus. You reflexively think about fucking (especially if you don't admit to it). You don't imagine rape. You work hard to not think about rape.

That's perfectly fine.
