What's all this nonsense?

In bell hooks' essay Postmodern Blackness, she says she was at a social gathering where she was one of two black people. The other black person in attendace said to her, "this stuff does not relate in any way to what's happening with black people." I would actually go further and say that postmodernism does not relate to any people. What is postmodernism, and why does it need to be talked about? I'm not sure bell hooks even knows.

In this essay, she discusses who discusses postmodernism. She never talks about the concept of postmodernism itself.

Why is postmodernism such an important thing to discuss, and why is it important that such discussions are inclusive of all types of people. What in God's name is 'postmodernist discourse.' Why is postmodernism even a subject of conversation? Who are these people that discuss postmodernism over dinner? I don't know anyone who does this? do any of you?

one last time: what is postmodernist discourse, and how does it relate to anyone? somebody please help me here.
