Why don't black people go on cruises? They already fell for that once
I am kind of shocked that you feel this way about black people. Have you ever been to a black country?
Look, we had slavery for so long. They are just stupid people who can't swim.
Believing that black people are both stupid and all cannot swim would be considered a racial stereotype and people who do that are considered to be racist. I don't think you want to be racist and just want to tell some jokes, so maybe you could chill on the more negative jokes and tell some lighthearted ones instead?
