I am not against a valid reason to have some venue to celebrate the works of a black anyone. For instance, I’d like to visit a place like that to see all the wonderful things that George Washington Carver did. Likewise for Louis Armstrong and the like.
But to promote a nobody (as far as I know) playwright simply because he was black isn’t something I care about. If he was somebody to care about, I believe I would have recognized him in some way or another. Even if by most standards I should have known, I really don’t care. To me, there is no ‘there’ there.
