They seem like a bunch of ignorant racists, and this is how the Guardian would like to depict anyone who isn't a multi-cultural progressive. In reality, a country has a right to protect its culture and to limit its intake of immigrants. As opposed to what the racists in the article think, immigrants actually enrich a culture and an economy. But, when you have such a huge mass of people arriving from a very different culture, it's very hard for to integrate them, it dramatically changes the characteristics of a country, and it's a recipe for trouble.
