There is also a fair amount of xenophobia inherent in the Swiss national identity. I know Germans who have lived there for 10+ years and are still considered outsiders.
There's definitely other forms of xenophobia here, though. There are a lot of negative stereotypes about some of the refugees that have come to Switzerland over the years, and many Swiss I talk to dislike the idea of refugees coming to Switzerland and choosing not to work (being unable to work is a different story).
I'm sorry, but who actually likes that idea?
Depends. Most are not, but in some cases, they are (e.g. islamic terrorism in France and Germany).
But the main reason is that some peoples/places have developed their own culture over centuries, and don't particularly appreciate some large rush of newcomers bringing their own stuff and messing the nice thing they have got going.
With respect to culture.... I don't know what to say to that. It strikes me as very xenophobic and more than a little naive. The way to get your culture to remain is by showing others what is to celebrate about it, not by forbidding them from living around you. It's not like any culture can exist long unchanged while children have access to the internet anyway.
For example, let's say you choose to eat unhealthy food, become obese, and land in the hospital. You might say "who cares what other people eat" while you are using a limited, shared resource.
If you're able to not work indefinitely because you're consuming a limited, shared resource like the money of other people that live in a country, why should they think that's fair if it's supposed to be a safety net?

Milk the hatred and distrust for the benefits (Always double-check on foreign science! ) and name it to everyone falling for it as what it is: Ancient Ape bugs. So mild mockery would be the best reaction i guess.
Social suppression seems to have failed on a large scale recently.
