(1) A special complication arises from the conceit to establishing vocational role models by showing the target audience actors who "look like them" in those roles: flooding film and TV with Black actors also reinforces the message that entertainment careers are more open to Black people than are other kinds of careers, which is one of the oldest and most pernicious "messages" American culture has been sending to Black people this whole time.
(2) Casting is and was always inherently unfair. Woke casting is not more or less fair than casting ever was. What's different about woke casting is not its fairness or unfairness but the fact that it is talked about openly and virtuously, even in the eye of the hurricane. For those thus located, this makes it divisive on a day-to-day, person-to-person level. (I am relating past and ongoing experience here, not conjecture.) So, whatever new society we're birthing this way, it seems the talent won't be sharing in it. Seemingly arbitrary acceptance or rejection is, as it turns out, a far stronger basis for esprit de corps. Arbitrariness is a kind of rugged equality, hardly the ideal kind, but closer to it than what is unfolding right now.
