What if it is a theatre company aware that its shows and casting disproportionately favor white actors and is attempting to fix that?
Because... that is the case of a lot of theatre companies. A lot.
And I love the "well, you should only cast the most talented people, regardless of race!" arguments- because where the hell are those arguments when a person of color is cast in a period piece, or when one member of a family is a person of color, and people here are saying it's distracting?
The fact is: the vast majority of casting for roles that are not race-specific will go to white actors. Why do you think there are all-black, all-Asian, etc. theatre companies? It's not to keep whitey down.
Unfortunately we are not at a point where "cast the most talented person regardless of race" is a thing yet, because too many directors and people running theatres will default when reading a play to seeing all white actors in the role and making that their "vision" for a production.
"...everyone finally shut up, and the audience could enjoy the beginning of the Anatevka Pogram in peace."
