Planetalism

Nationalism on a planetary scale. Planetalism teaches you to take pride in things you have never done, while hating aliens you've never met. Not to be confused with Planetism, which is simply favoritism of your own planet, without regard to alien species.

Don't assume all Earthlings are good and all Mars folk are bad, that's Planetalism.
