That's awful, do you think it's okay to joke about molesting a child?
Put yourself into my position and think
You shouldn't be making jokes about child rape. Don't you think that could be a little bit hurtful towards victims?
I'm only joking.
To you it might just be a joke, but the thing is that children are raped and molested often, so it isn't an appropriate thing to joke about. Find a way to be funny that isn't offensive or hurtful to victims of this sort of thing.
