Morty: Okay, yeah, but I don't think it's about logic, Rick. I, I think the word has just become a symbolic issue for powerful groups that feel like they're doing the right thing.
Rick: Well, that's retarded.

When Rick and Summer are brought to be judged, the hand throne has Latin writing on the steps. "Sis semper calumniam" which means "constant oppression" (literally "you always oppressed").
