why are black people so good at basketball ? because they can run , steal , and shoot .
I'm uncomfortable with the racist nature of this joke.
Don't try to make sense of it. Simple, blacks are criminals and socially disadvantaged.
Jokes like this one perpetuate the stereotype that black people are criminals. This stereotype is harmful to black people, and we shouldn't be saying things that reinforce it. I'm sure you could find better jokes to tell.
