Diversity in focus, as black actor in Harry Potter role

In spite of the changes at presidential level in the United States since 2016, gender diversity is on the rise there. Recent elections saw record numbers of women enter congress, including Alexandria Ocasio-Cortez, of Puerto Rican heritage, and the youngest ever congresswoman. Hollywood is diversifying too, with a black actor, Noma Duezweni, just cast in the role of Hermione.
