"When I began writing science fiction, when I began reading, heck, I wasn't in any of this stuff I read. The only black people you found were occasional characters or characters who were so feeble-witted that they couldn't manage anything, any way. I wrote myself in, since I'm me and I'm here and I'm writing."
