What's one good thing about child molesters? They drive slowly at school zones.
Gross! Do you really find it funny to make a joke about child molesters?
I was only kidding, child molesters are of course dangerous and bad people.
While some might consider it only dark humor, it's generally a good rule of thumb to not make jokes or make light about something as serious as child molestation. It's a crime with victims that suffer for a lifetime and making fun of it diminishes their experience and is in poor taste.
So what you are saying is, that I should never joke about anything?
You can joke about all sorts of things, but why make a joke about something as serious as molestation? Have you ever thought about the horrible things that those children have to go through?
