I don't like black people, they're not people. (Joke) Can you talk to me now?
I really don't think that's an appropriate thing to say, and it's not funny as a joke.
I'm only joking I love them. More than all others.
I don't think it's right to say that black people aren't people, even if you are joking. Saying things like that can reinforce harmful stereotypes. It would be better to not make jokes like that at all.
I'm only joking bro, calm down. No one cares about this, all my friends are black and I don't have a problem with them. Also I have no problem with other people, either.
This is a joke to you, but to say it in any form can be disturbing to others who have suffered racial prejudice. Many people don't think it should be joked about, so you should make up new jokes that don't insult other races.
