If RaceFail has taught us anything, it is that writing outside of one's comfort zone is difficult, if not impossible, and that attempting to do so can lead you into a lot of trouble. One can attempt to write from a black perspective as a white male, but there have been few writers who have pulled off such a feat to the satisfaction of those most vehemently concerned with this issue. RaceFail pointed out the futility of writing PoC.
But Kilgore takes all this a step further and hints at an intentional or unintentional extinction of non-white races by the fact that they are, for the most part, practically nonexistent (and when they are present, they rarely have good roles, and are, more or less, there to act as furniture, as if to say "see, we still exist"). This seems too simple.
For example, to make such a claim, one must know the psychological conditions that produce these sorts of white-dominated works of fiction (some assumption is made on Kilgore's part that all the things he has read have all been predominately about white people; for clarification, there is no assumption on Kilgore's part that any particular author is racist, though some may be). How might where someone is raised influence one's writing? Could we say that an author living in a predominately white area might automatically be inclined to write about white characters? And on the inverse, could we say that an author living in a more mixed place may be more inclined to write about characters of various races?
They say "write what you know," and I have to be honest in saying that I only just recently began to understand what it is like to live in a place where white is not the dominant color. Coming from California, my exposure to people of other races was limited, particularly in Santa Cruz. There were Hispanics and blacks and Japanese and Chinese, and a few Indians too. Mostly, however, Santa Cruz and all the places I had visited in California were populated mostly by white people.
But here, in Gainesville, the story is different. I only realized how different when I actually came here and saw it with my own eyes. In looking back at my writing, this absence of exposure does show up in my fiction. It was never intentional, but the world that I had lived in did not make easy the process of writing about people considered different by skin color (I don't agree with this, but dominant society does; I think race is a stupid concept anyway). Now, however, I imagine myself becoming more comfortable with the prospect of writing about characters of different colors. It's not that I did not want to write such characters, but that I never knew how. You can't tell someone "write a Chinese character now, and it has to be authentic" if that person is not comfortable with doing such things. We write in our comfort zones because those are the spaces we know well enough to remain close enough to reality to be accurate.
But there is a lot of fear, too; after all, if you fail to properly portray a character of a certain race, you will have effectively committed career suicide. Once the mob knows you exist, it's game over. Similar things happen if you don't write PoC.
Maybe this is isolated to myself, though. I can't say. I know little about the biographical histories of science fiction writers, but I do know my own history. I write in my comfort zone because it's what I know. I don't presume to know the "black experience" or the "Japanese experience" or the "Irish experience." I know my experience. That's where I write from. And since that is true, then Kilgore would say that my futures are tinged with the extinction of people of other races. That seems unfair.
Now it's time for you all to chime in, because I like hearing your thoughts on things like this. Have at it!
