A paper on Psychological Differences between citizens of the West in comparison with other cultures. Here is a sample:

In the eyes of most Westerners it looks immature and childish when people try to use threatening behavior, to mark their dislikes. A Danish saying goes “…Only small dogs bark. Big dogs do not have to.” That saying is deeply rooted in our cultural psychology as a guideline for civilized social behavior. To us, aggressive behavior is a clear sign of weakness. It is a sign of not being in control of oneself and lacking ability to handle a situation. We see peoples’ ability to remain calm as self confidence, allowing them to create a constructive dialogue. Their knowledge of facts, use of common sense and ability in producing valid arguments is seen as a sign of strength.

The contrast follows, and this only relates to dealing with anger. Other issues are discussed as well.
