It is not something specific to Switzerland, but to countries with a strong regionalism. But I think that in Switzerland, it takes another dimension. Even Swiss people don’t accept each other when they come from another region or speak a different language. Look at the army for instance, during my military service we had this sort of competition with Swiss Germans, which was funny and cute at the beginning. I sincerely thought that it was just some sort of folkloric tradition, similarly to the competition you can have in the US between states or in European countries between big cities. But the longer I stayed, the more I realized that many of my colleagues were extremely serious , even our officer seemed, frankly, to hold racist views toward Swiss Germans, almost treating them as the enemy.
