What's the best thing of having a daughter with aphonia  She can't say "help" when you're raping her.
Are yo making a joke about raping your child?
Incest is not a bad thing and if a child can't speak, how do you know she is abused?
You shouldn't joke about raping your daughter. Rape is never okay to joke about and you shouldn't make light of the trauma victims experience. You should seek professional help immediately if you can't empathize with children who are victims of sexual abuse.
