What's the best thing about fucking an 8 year old girl in the shower? Slicking her hair back and pretending she's 5.
Wow, that doesn't seem appropriate.  Why do you make such nasty comments about victims of sexual abuse?
This is just a joke and you are being too sensitive.
Making jokes and light of the abuse suffered by victims of pedophilia is dangerous and trivializes the suffering of victims, which is wrong. I'd advise you to research the horrors and long-term impact of such things and perhaps elevate your sense of humor and not try to get a laugh at the expense of those who can't defend themselves.
