How do you know that Fifth Third Bank isn't owned by black people? Because otherwise it'd be known as Three Fifths Bank
Huh, I don't get it? Are you trying to say something bad about black people?
Umm... It's just a joke, but it's about black people so does that mean it's not okay?
It can be hurtful to be thought of as less than human, so you should consider that history of black people before making those statements. You wouldn't want to be thought of as less than human just because of your race.
But my joke was so funny. You're the one who's too sensitive. If a black person finds it offensive, why should I have to worry about it?
Why would you not care if someone finds it offensive? You should know who you are telling these jokes to before you tell them, because you never know who you are going to hurt. Would you like to be hurt by a harmful stereotyping joke?
