I don't think of myself as a metafictional writer at all. I think of myself as a classic writer, a realist writer, who tends to have flights of fancy at times, but nevertheless, my feet are mostly on the ground.
I'm not an optimist. I'm a realist. And my reality is that we live in a multifaceted, multicultural world. And maybe once we stop labeling ourselves, then maybe everyone else will.
I think there's a joy to be had in taking readers where they just don't want to go. If you are writing a properly realist novel, then don't blink. Why not see something for what it is and render it truthfully? I find it a good way of going about writing - not to blink.
I don't personally consider myself Dr. Doom. I call myself Dr. Realist, even though it's less exciting and more boring than being called Dr. Doom. If you are consistently saying 'the world is going to end,' who is going to listen to you?
If you are a novelist of a certain type of temperament, then what you really want to do is re-invent the world. God wasn't too bad a novelist, except he was a Realist.
When I was younger, I was somewhat of an idealist. I guess I'm a little bit more of a realist now. I think there's a lot that can be done to make the world a better place, but it's more about choosing your battles.
