What's the difference between a baby and a loaf of bread? What you cut the bread it doesn't cry.
Is this meant to be funny? I find that joke upsetting.
It was absolutely supposed to be funny. What else would it be? It's just a simple fucking joke.
I don't think joking about harming children is very funny. When people joke about harming children, it helps to normalize the behavior and can make people feel like it's an acceptable thing to do. People will also be upset if they hear you tell jokes like that one. I think you should tell family friendly jokes that everyone can enjoy!
