Its hardly surprising - the islander thing you refer to. Islander males express themselves through fighting - look at the over-representation in violent sports like League, Union, boxing and MMA. What is the hakka about? It is basically a threat to kill their opponents and dump their bodies in a ditch. It always amuses me that their opponents are expected to respectfully observe this 'cultural' display.
When this islander macho culture meets our own worsening anglo-celtic binge drinking culture (ie Sydney) we have big law and order and safety problems ie Sydney.
