Do you know why black people are fast? Because all of the slow ones are in jail.
I get the joke, but I want to hear what you think about the joke's connotation. It seems pretty racist to me.
It later developed into a spell: "But the joke is black and sees"."
This joke is based on a racist myth in the United States that all black people are criminals. Telling this joke only perpetuates the myth harming race relations in the country. It's better if you find jokes that aren't race based to tell.
What? I can't believe you can force me not to joke about anything. Where does it say that I'm forced to tell a joke that's not offensive to anyone?
I'm not telling you not to joke about it, just that believing that black people are all criminals is in extremely poor taste. People are going to think that you are racist and not want to hang out with you.
