Ask the Chinese or Koreans how they feel (gutturally) about the Japanese. Ask the Japanese how think of the SE Asian populations. Ask the Brahmans what they think about the outcasts (which includes all Westerners).
Ask the Poles about their “Ukie” jokes, but don’t share any Pollack jokes with them.
