Jive-talking black crows, smoking while singing, "I'd be done see'n about everything, when I see an elephant fly" is already super offensive. Except it gets worse. The main crow's name is Jim Crow, hilariously named after the racial segregation laws. Additionally, the actors are all white men putting on their best black man voice. Yes, the beloved story of an elephant who learns to fly is just a dressed-up minstrel show. The defense Disney super-fans give the characters is that they were the only ones who helped Dumbo. But just because they're nice doesn't mean it's not racist.
