It makes sense and I don't disagree with the bulk of what you say here.
But I don't want to open up the can of worms that will come if we start discussing "for white audiences" and such. I'm definitely not someone who thinks that Caroline or Change isn't "okay" or "valid" people it was written by a Jewish man who is white (whose life it was taken from, and whose own self as a child was the basis of the other half of the show, and whose relationship with the woman Caroline is based on is why the show exists) or a female composer who is white. I'm not going to agree that... what... Shuffle Along was created by George C Wolfe "for white audiences", or that... productions of Hansberry or Wilson are done "for white audiences" specifically or in a bad sense. And there's a LOT to break down here because "white audiences" are largely who pay for broadway tickets, as it currently is. There are many reasons behind this, many ways this will hopefully change and quickly. There's a LOT here and it's not as simple as I think your post makes it out to be, from a commercial or artistic view.
I'm already in too deep... this is a whole other conversation that is worth having but not tonight and not in this thread.
