You do not judge people by they're true ethnic background; rather, you judge them by how rebellious their faction of origin was in your Campaign. "Filthy Gauls" (french)
You think it is disrespectful if someone does not complement you by saying "You are the best unit your faction has to offer."
You go out on the street and offer people map information in exchange for an alliance against those filthy Julii."
After you tell your neighbors they are making to much noise you offer them a written treaty that declares a ceasefire. In small print it says: Accpet or we will attack.
