The Associated Press writes about a recent Swiss election:
The party is seeking to whip up enthusiasm for a deportation scheme that anti-racism campaigners say evokes Nazi-era practices. Under its proposed law, entire families would be expelled if their children are convicted of a violent crime, drug offenses, or benefits fraud.
If approved in a referendum, the law would be the only one of its kind in Europe.
Now, of course, Switzerland was never a Nazi country (I suspect had the Nazi's tried invading, they would have been humiliated—the Swiss have a true national defense force, not an imperialistic military industrial complex subject to perversion via political con games).
Democracy in Switzerland goes quite a bit further than in the US. The BBC reports:
The report, from Switzerland's Federal Commission on Racial Discrimination, recommends far-reaching changes.
Muslims and people from the Balkans and Africa are the most likely to be rejected, the report points out.
Switzerland has Europe's toughest naturalisation laws. Foreigners must live for 12 years in a Swiss community before they can apply, and being born in Switzerland brings no right to citizenship.
Basically, between referendums and strong legal protections, the Swiss bureaucrats can't elect a new people as easily as their counterparts in the US. Of course, as the failure of US immigration policy becomes more apparent, I expect there will be a strong reaction from folks in Europe.
The simple fact is that replacing the existing populations of developed countries via mass immigration depends on centralization of media, political and economic power in rather few hands. No truly democratic regime would ever do such a thing.
