Rather a blanket statement.  Majority of people don't.  I've seen people lose their calm when I was studying abroad in Germany.  Saw people loose their calm in France and Spain as well.  Back to your question, though, calm people don't make headlines. The media in the USA loves drama caused by fuckwads.  Ergo, the international community is going to see news stories about fuckwads with short tempers. Here's something for a tangent.  All we in the USA see of places like India is mass gang rapes.  If I apply your blanket logic, why do men in India all seem to rape so much?  (Rhetorical)
