I've often pointed out that negroes are more stupid than I can even imagine if they actually think they're gonna win any race war.
Can you tell me more about how you feel about black people?
They're stupid and they're inferior. Just kidding. You don't have to be mad.
Even if those statements are jokes, calling black people stupid and inferior causes more racism. If people regularly make racist jokes about black people, eventually people will actually start to believe these jokes as facts. You should read up on the history of racism so you can be more open minded.
