Detrimental Media and Natural Reflexes of Race Relations
Someone who lives in an ethnically homogeneous society ( or at least one that claims itself to be ) often requires a visually exaggerated definition of race in order of make sense of distant peoples they often cannot meet in real life. Oh ok, Italians eat pasta, Japanese eat sushi, Americans eat hamburgers...thats all harmless and well if one never gets to meet an Italian, a Japanese, or an American. Whatever it takes to help people remember different peoples and their practical differences, then, would prove somewhat valuable for, say, watching TV or going for short tourist visits in foreign countries.
