The Swiss are civilized, right?

From Patterico.com:
The majority Swiss political party is now campaigning to "make deportation compulsory for convicted immigrants rather than an optional and rarely applied punishment".
One of the issues, apparently, are federal statistics showing that “about 70 percent of the prison population is non-Swiss.”
The campaign "has turned into a nationwide debate over the place of immigrants in one of the world’s oldest democracies and over what it means to be Swiss".
If they can have such a debate, in "one of the world’s oldest democracies", why can't we?
