I don't think PJ was joking. But I don't think he is saying it's not a racist song or that he doesn't understand what they're trying to say with it.
I think (and yes, I'm speaking for him ...) his point is that he feels it was irrelevant to this particular story. It pulled him out of the events at hand and the characters on stage.
My posts counter about the relevancy to the story and to these characters.
But I don't think he's saying they are pointless or that they aren't racist. He just thought it wasn't necessary in this particular play to bring up the issue of racism.
And I disagree! I thought it was handled beautifully. And I thought it made these characters more interesting to understand their world and their views of it on a much deeper level.
