I have to wonder if the creators of the film knew what a profound statement they were making when they wrote this scene. The point, of course, is that people and things are the way they are; they comprise a reality that we didn't create and cannot deny. Therefore, pointing out that someone cannot act contrary to reality is not actually an act of oppression, no matter how much certain activist groups want to portray it that way.
Go read the whole thing. It's excellent.
