The US is a cultural hegemon so it is often picked on. There are tons of idiotic peoole and cultural practices here in Spain. But the rest of the world isn’t really aware… I mean I don’t blame them. One cannot keep up with everything.
But believe me, stupidity and insular thinking is just as endemic here as it is in the States. It just annoys me when “enlightened” Americans habitually paint other Americans as somehow dumber than dumb people elsewhere.
