When I lived in Barcelona in 1980-81 and 1986-87 I encountered many Spaniards who had moved there, lived there for decades and never learned to speak Catalan. They refused to learn it with the arrogance of conquerors. Their listening comprehension of Catalan would improve instantly when I responded to their "sí no me hablas en castellano, no te entiendo" with "I'm American, do you prefer English or Catalan?"
The idiocy you describe is borderless because the mother of the idiots is pregnant everywhere
