A black man walked into my store and bought some polyester pants It's weird because they usually pick cotton
Come on, why do you have to make everything a racial joke?
Well because of the fact, back then black people all wore cotton and wore them in their natural skin tone but nowadays these black folks need to make all sorts of excuses.
It is not a good idea to make light of the fact that black people used to have to pick cotton as slaves on a farm. Whether your intention was to be funny or not, this is a very insensitive joke.
I was being sarcastic. What do I do now?
You can apologize to begin with. You can also study history and try to learn about what happened on a cotton plantation. It is unfair to see an entire group of people as slaves.
