Haha, see? I told you Obama's not human--he's a gorilla!
What's wrong with you? Are you making fun of black people by comparing Obama to a gorilla?
Naahh. I'm just joking bro. Meaningless joke you know?
While it's good to make jokes, I would not do so when it comes to making comparison between races and animals. It's not right to insinuate that black people are like gorillas since it spreads the harmful belief that they are less evolved than other races. It's okay to make fun of Obama if you don't like him but it would be best not to make any jokes involving his race since it can spread racist beliefs and that would negatively impact society.
