More Hateful Jokes About African Americans

Don't get me wrong, I love to hear jokes, but at what point does a joke become a racist comment. How many more "black jokes" compared to "white jokes" have you heard that have negative connotations. Well for me, society has created a world where in my personal life, I rarely hear white jokes that insinuate that whites are awful human being who cannot support their family or live in a successful manner. Many who make racists jokes say that it is easier to think of a black joke that is funny and many believe to be true compared to any other race. Listed below are several blacks jokes that I have heard. Many are piercing to your morality, but the importance is to show that white Americans still feel like they have more power and success compared to a black person.

These jokes have unfair connotations to African Americans. Blacks should not be at the center of racists comments. Yes, they may appear to be jokes, but many of these jokes made me cringe and I am a white teenager, so I cannot imagine what it would feel like for an African American to hear these jokes. Something needs to be done, but what is it?
