From Moscow to Marseilles, from Stockholm to Sicily, they see the Muslims pouring in and creating tiny nations within the nation, and being unwilling to embrace a new identity as Englishmen, French or German.

And their fears are not unjustified.

For just as the populist parties are deeply ethnonational, proud of their identity as Swiss, Austrian, German, English, Dutch or Flemish, the newcomers, too, are deeply ethnonational: Turkish, Arab and African.

And Islam is a faith that is itself anti-multicultural.

Devout Muslims do not believe all religions are equal. They believe there is one God, Allah, and submission to his law is the path to paradise. They do not believe in freedom of speech and the press if it means mocking the Prophet. They do not believe in Western dress codes or mixing men and women in schools and sports. They do not believe all lifestyles are equal. Some think adulterers should be stoned and honor killings are justified for girls who disgrace the family.

They wish to live their faith and their culture in our countries, to live alongside us but to dwell apart.

“If you come to France,” said Sarkozy last week, “you accept to melt into a single community, which is the national community, and if you do not want to accept that, you cannot be welcome in France.”

A little late for that. Some 5 million to 8 million Arabs and Muslims are in France, their birth rate is higher, and more are on the way.

The real questions: Whose idea was it to bring these people in? And what do France, Britain and Germany do if they say: This is a democracy, we will live as we wish to live, according to our beliefs, not yours.

How does a liberal, permissive society that celebrates diversity impose its values on a militant immigrant minority that rejects them?

Answer: It doesn’t. All the rest is chatter.

This is what James Burnham meant when he wrote that liberalism is the ideology of Western suicide.
