Just starting planning out My Great SF Novel. It's gonna have lotsa different aliens in it, and I'm looking for an inoffensive way to write about them. Are the Blurghs a violent alien species or race? Are the Martians an elusive race or species?
I don't want to be offensive. I do want to be as scientific accurate (What?! In a SF novel you wanna be accurate? Don't quit the day job, muppet!). So: species or race?
