The race riots in China between the Han and the Uighur ethnic groups is proof once again that multi-culturalism can never work.
Lets look at history ;
The multi-cultural Roman Empire under both Dictatorships and the Republic failed to ensure peace even using the most violent tyranny in history.
The multi-cultural Egyptian Empire failed and descended into war and chaos.
The British Empire collapsed into racial, religious and ethnic conflict such as Partition in India.
The Soviet Union collapsed and the nation states under the Communist jackboot returned to nationalism in a frenzy of war and ethnic conflict.
The American multi-cultural society is the most violent on earth - the gang war between the Bloods and Crips has killed 5 times more people in Los Angeles alone than in Northern Ireland during the Troubles. Then we have the crime rates of Black on White crime, and facts such as more people died in America from gun crime during the Vietnam War than American soldiers in Vietnam.
Now the Chinese model is breaking down.
Every model of multi-culturalism throughout history has failed - and they have all collapsed into race wars, civil wars and resurgent extreme nationalism.
From Dictatorship, Communism, Roman Imperial Fascism, Monarchy, Democracy and Tyranny - each of these political models have failed to ensure the viability and cohesion of any multi-cultural society.
Multi-culturalism is the seed bed of chaos and war.
The aim of multi--culturalism is simply for the elite to grow rich whilst the masses grow poorer.
The result of all multi-culturalism is simply the prelude to civil war.
Continuing down the path of multi-culturalism is either insanity or the deliberate attempt to start new wars for profit by the elites.
