We don't claim that all these types of behaviour are exclusively typical of these nationalities, only that they are very commonly either false or exaggerated perceptions of certain countries. Most of the time these images were created by popular books, comic strips, animated cartoons, films or propaganda, and other times promoted by the country in question. We're listing stereotypes here, which means that we list all these recurring caricatural ideas about other nationalities that can be found regularly in any work of fiction.
So no racist or discriminatory quotes claiming: "Hey this stereotype is actually true" or aggressive, offended comments like "Hey, my country or people are nothing like that!" Most countries depict their neighbouring countries as if they are all either lazy, evil, dumb, primitive, ugly or arrogant. Nothing new there and it proves that these stereotypical impressions about other countries are universal, rather than tied to one specific country.
We can also miss proud, arrogant, patriotic boasting remarks like "Our country is uniquely very good at this or that", which is usually also very narrow-minded nationalism. Behaviour cannot be restricted to an entire race, culture or country of people. Not all Americans are obesegun nuts, not all Britons are austeretea lovers, not all Frenchmen are arrogantcowards, and not all Asians are aphorism-mumblingmartial arts experts. Each country has claims to have their own specialties, unique drinking culture (beer, wine, tea, coffee,...) and a reputation for being hospitable.
