Thanks. I'd like to read it but I don't speak German unfortunately!
Would be odd but not unprecedented for someone who is the child of an immigrant to have negative views of immigration. And he's also lived in London for a long time, a city that has constantly evolved through the coming and going of different people.
His father was Hungarian, a country based on Western culture. Obviously, most of the complaints about mass immigration are about non-Western immigration. For example, in my country nobody has issues with immigration from Ukraine, Moldova or Bulgaria.
Anyway, you can read the interview with the help of Google Translate. Just translate the picture and you won't need German, although it helps you to understand the flow of the conversation, of course.
