facts simply show that the imperium is not really doign anything for cooperation or acceptance of other humans, it only does subjugate and has actually never done anything else but impose it's own ideals and methods on others, by force if neccessary (and mostly it was and still is deemed neccessary)

xenophobia is more seen as fear/hatred directed towards others/outsiders... you can be xenophobic and still display contempt/disliek/violence towards others on a basis of them not sharing a certain definition with you

racism is based on whatever idea of "race" you have.
