Coworker #1: Hey, Shaniqua can you hand me that coffee?
Coworker #2 (very angry): My name is not Shaniqua–that's racist. Just because I'm black doesn't mean I have a name like that.
Coworker #1 (defensively): That isn't racism–it's a joke. Calling someone by a name that isn't theirs isn't racist. You shouldn't be so quick to call someone a racist.
Coworker #3 (after some consideration): I thought about what you said earlier and you're right. Besides, everyone is racist to some degree. Even myself. I find that I'm racist against fat people even though I don't mean to be.
