Why are you making a joke about mental difference between a gorilla and a black man?
It's not a joke!
Black people have a difficult time already with a lot of injustice just based on their skin color and the way they tend to be portrayed by the media and by society, so it is hurtful to think people think that you are dumber than an animal. You would not like it if people implied that you were dumber than an animal based on your skin color.
