In fact, this is a tenuous conclusion to draw from the evidence. Many languages refined their identification as "the true people," or "the real people," dehumanizing the other people or simply considering them inferior. In this, it is merely evidence of ethnocentrism, a universal cultural characteristic found in all societies."
