Why deport immigrants? (Right wing focus on immigration globally)

The world as we know it emerged out of the ceaseless wandering of humans on the planet and, more recently, with migrations of millions across national borders. That trend of globalisation could be reversed as growing numbers of political parties and movements around the world call for sterner restrictions on immigration and immediate removal of those unlawfully residing within their countries.

This could be more than an empty threat as such parties gain in established democracies. Examples abound: the Dutch Freedom Party, the German National Democratic Party, the British National Party, the French National Front, the Italian Northern League, the Irish National Party, the Israeli Yisrael Beitenu, the Indian Shiv Sena, the Sweden Democrats Party, the Danish People’s Party, the Spanish People’s Party, the Norwegian Progress Party, the Austrian Freedom Party, the Flemish Interest Party, the True Finns Party, the Swiss People’s Party, the Australian First Party and the American Tea Party.

Resistance to immigration, running against the modern tide of globalisation, is an early and major plank for many of these political parties. Particularly visible and forceful, often striking a sensitive nerve among much of the public, is their fierce opposition to illegal immigration. For example, a year after voting to ban minarets, Swiss voters in November approved the referendum backed by the right-wing Swiss People’s Party for automatic deportation of foreign-born nationals convicted 
of crimes.

Fueling calls for increased deportations are frustrations and disappointments with multiculturalism and assimilation, contributing to anti-immigrant sentiments. Various national leaders and party officials — most recently in Germany, the Netherlands, Sweden and Switzerland — have expressed serious doubts about the success of immigrant integration, especially among those who differ religiously and ethnically from their host communities. Remarks by German Chancellor Angela Merkel, for example, were unequivocal with regard to immigration, stating that attempts to build a multicultural society, living side by side and enjoying one another, have utterly failed. Some go further, such as the leader of the Sweden Democrats, claiming that the population growth of the Muslim immigrants was the greatest foreign threat to his country since World War II.

That's quite a comprehensive list of far right parties, although the "Tea Party" is hardly a party.
