What's the worst thing about 10 dead babies in a barrel? Not a one of them is black.
You're saying it's a bad thing when a black baby doesn't die?
Yeah, but it's just a joke. Why are you taking it so seriously?
I'm taking it seriously because I think what you said was really mean and heartless. Making jokes like this can be harmful and make people feel terrible. I think you should try to be more considerate to others' feelings when you make jokes.
