In this Science fiction question, I use the world "Racist" to describe the human predominance of the Empire, in Star Wars.
Someone suggested xenophobic :
Well, this is getting a bit into anecdotal territory, but every Science Fiction piece I've read used "xenophobic" to describe those that hated other species. It may be that you need to further define "foreign." All you have to do is take the existing definitions, and extend "species" to the locality qualifier. This isn't unreasonable, and given that the whole idea is something we have not had to combat yet I find it entirely accurate.
Is there any better word to define this fictional problem?
