There's such a thing as historical accuracy, people. Yes, there is, and I'm perfectly satisfied applying it to costumes and not skin color.
When I was 16, I waited in Central Park all day to get a ticket to see Stacy Keach as Hamlet, Colleen Dewhurst as Gertrude and James Earl Jones as Claudius.
It remains one of the most powerful evenings in theater of my entire life. If you think I or anyone in the audience was bothered for even a fraction of a second by the color of James Earl Jones's skin, I pity your lack of imagination.
The summer before I had seen Two Gentlemen of Verona, with Raul Julia and Clifton Davis. The production was so much fun it won the Tony over Follies. No one in the audience worried for an IOTA of a second whether or not 16th-century Verona had black or Puerto Rican people.
Since then I have seen many color-blind productions, and unless issues of race are involved in the plot, I see no reason why it should not be the norm.
Whatever you have in your mind about "historical accuracy, people" seems more like thinly veiled racism.
