Mike Epps got a lesson in racism -- the comic actor got blasted on social media for posting a photo of a black man whipping white slaves.
Epps posted the pic on Instagram and Facebook late Thursday night -- and the cotton field scene also included an image of Dr. Martin Luther King Jr. floating above ... and smiling. Epps captioned the image, "I am so proud of you bro! Lol."
Something Went Wrong
Epps -- who's playing Richard Pryor in an upcoming biopic -- quickly took down the photo, but not before getting an earful from angry fans.
