I have trouble sorting out whether this article is meant to be satire.

"As a rule, ethnic nationhood is a terrible idea – an idea that, after it sprang into popularity in the late 19th century, was responsible for many of the worst atrocities and horrors of the 20th."  

No, the horrors of the 20th century can be attributed to socialism:  Stalin, Mao, Pol Pot, and Hitler's National Socialists among others.

"As Canadians have learned the hard way, it is far better to encourage the formation of multi-ethnic federations with special distinct society rights for regionally concentrated minorities."

All citizens of a country should be treated equally without special rights for designated victim groups.  Look at the mess we have made in this country with handouts to Quebec and special rights for a certain ethnic group that can not be mentioned.

It is not just that the writer is wrong, but he offers no supporting arguments for his ridiculous assertions.  A very weak article indeed.
