Olivier Award-winning actress Noma Dumezweni is playing Hermione in the new play Harry Potter and the Cursed Child, and although you would think that people would be happy that an accomplished and qualified actress will be stepping into the role, racists everywhere are whining that only a white woman should be playing the part. J.K. Rowling discussed the controversy surrounding the casting in a recent interview with The Guardian

With my experience of social media, I thought that idiots were going to idiot. But what can you say? That’s the way the world is. Noma was chosen because she was the best actress for the job. When John told me he’d cast her, I said, ‘Oh, that’s fabulous’ because I’d seen her in a workshop and she was fabulous.
