Xenophiles are those who are comfortable with people who aren't like them. Xenophobes hate and fear people who are different. They are only comfortable with people who are similar to them. The xenophobes don't understand xenophiles. In fact, for them xenophiles are among those who they hate and fear.
I have always identified science fiction as a xenophile genre. Of course science fiction isn't all xenophilic. There's xenophobic science fiction and it's immensely popular. Yet being a xenophile is a possible approach to science fiction. There's a whole tradition of science fiction that's created by and for xenophiles--most notably Star Trek.
As I read the third Binti book by Nnedi Okorafor, it occurred to me that I like Binti because she's a xenophile, and that her series of novellas is really about the conflict between xenophiles and xenophobes. I expect that Okorafor is likely to be a xenophile herself or she couldn't write sympathetically about Binti.
In Binti's world a xenophile is called a harmonizer. They have a gift for building bridges between disparate groups, and finding common ground. In our world the harmonizer is called a diplomat. Xenophobes have tremendous contempt for diplomats. They don't believe that any rapprochement with those who are different is possible. They are resolved to either avoid those who are different or kill them. When a harmonizer or diplomat is negotiating on behalf of a xenophobe and/or attempting to reach an agreement with a xenophobe, they are in the most challenging situation they will ever face. Binti ends up in this situation in Binti: The Night Masquerade.
Since the events of this third book are so climactic, I somehow doubt there will ever be a fourth one. If there ever is another Binti book, it will probably focus on another way of being a harmonizer which is mentioned in relation to Binti's fellow harmonizer, Mwinyi. Perhaps there will be a Mwinyi trilogy. I would look forward to that.
