What does that have to do with anything? There's many examples of minorities being used in media that promotes stigmas and stereotypes of their groups.

Race fetish porn is a huge thing and it features racist tropes against non-whites. The black men in the videos are portrayed as beastly sex machines. They purposefully pair darker-skinned black men who are taller and larger in build with petite, slender blonde women (to highlight the "animalism" of the black man and the powerlessness of the "pure, innocent white girl") and make a big deal of portraying the black men as having giant penises which are "destroying" the orifices of the white woman. The really trashy videos in this genre have the white woman hurling racial slurs at the black actors, too (including "n**ger"). (There's black woman/white man porn that is also racist, portraying black women as "black whores". There is also racist cuckold porn.)
A lot of hardcore rap culture is often criticized as a modern form of minstelism for promoting harmful stereotypes of black culture (ultraviolence, gang culture, crass materialism, anti-intellectualism, racist sexual stereotypes, etc.).
There's similar examples with other ethnic groups and with LGBT people, too.
I'm sorry, but I fail to the see the humor in making fun of someone's skin color, especially in a social context where darker skin is vicariously maligned and exoticized/fetished. A white girl in high school tried to make a joke about me being a slave and I was confused. I wondered what she meant and she put her arm next to mine, meaning that because I have brown skin, I'm a slave. I was not amused.
